First of all, I would like to thank Aunt Zhang for letting me win this public exam. I have lived for so many years, and only two bags of washing powder were won in the lucky draw and lucky draw. This time, I was selected by Aunt Zhang from more than 5,000 people and became one of the lucky ones of 10. I just want to say: Aunt Zhang, I love you! Well-designed good product, Aunt Xiaomi weighing scale evaluation report. Actually, I want to tell you quietly that I want DJI.

Perhaps my comprehensive evaluation scheme won Aunt Zhang's favor. Let's start this evaluation according to the plan.
First, Xiaomi weighing scale packaging
Aunt Zhang gave me a gift, and I got the imperial seal, which was full. It's also padded with bubble paper and packed very carefully.

Xiaomi's ancestral packaging box has its own style. But this time the box is a little big, compared with the box of Mi 4.
A good product designed with heart, Xiaomi weighing scale evaluation report
In addition to being large, it also has a considerable weight, with a gross weight exceeding 2kg and a net weight of 1.9kg, which should be the second product of Xiaomi. The first is Xiaomi TV.

The first time I saw these signs on the millet box, it was because there was a large piece of tempered glass inside.

The product information on the back of the box, produced by Huami Technology, is of the same origin as mi band, and * * * uses an APP, as shown below. The corner of the box fell flat, the scale inside was intact, and the packaging passed the test of violent express delivery.

The unpacking process was skipped. Weighing scale is covered with an extra-thick cardboard, which is very strong and can be used as a shield. It seems that this precious glass needs careful care.

Second, the appearance
This evaluation adopts comparative method. The products used for comparison are MacKay, Lemon, Bluetooth weighing scale on the left, and Belida Mechanical weighing scale on the right.

Let's look at the appearance of Xiaomi weighing scale, which is exquisite and simple, with white glass without borders and rounded rectangles. Cook: I want to sue you for appearance infringement. Lao Luo: Shit.
The front dimension is 300mm square, which is one circle larger than the average weighing scale. My feet are 27cm long and stand just right. My feet won't hang outside weighing scale, which is very comfortable. The other two weighing scale models are a little small for me, and it is awkward to stand up. There is another advantage of large area. Babies who can't stand by themselves for several months can sit on it and weigh themselves. This should give Xiaomi a compliment.

The chamfer of the glass edge is very round and delicate.

Mclaren also adopted the same process. This craft is very common in furniture, and it can also be used to decorate small shops selling glass in the city. It seems very mature.

Compared with the display area, Xiaomi is a 16 1 white led, which is full of science and technology. Mckay is a traditional LCD screen with blue backlight. At present, most electronic weighing scale on the market have adopted a scheme similar to McLaren's, and Xiaomi has completely won in this respect. At present, Xiaomi weighing scale's screen can only display numbers without units. With the upgrade of firmware, Chinese can be displayed. After all, the lattice density is enough. This is also Xiaomi's consistent strategy, using usable hardware, and gradually improving its functions through frequent updates of software in the later period. There is also a light sensor under Xiaomi's screen, which can adjust the brightness according to the ambient light. You can't shoot without a macro head in your hand.

Thickness contrast, millet 28mm, wheat 20 mm. Wheat is light and thin, millet is slightly heavier.

On the back of millet, white ABS plastic, four pads with built-in sensors, and a battery compartment in the middle.

Foot pad comparison. Wheat straw mat is made of integral plastic, which is dustproof and waterproof. Xiaomi's foot pad, whether sealed or not, can't be seen from the outside and shakes loosely. Under the bed and sofa, there is a hidden danger of dust.

Battery compartment, four fifth batteries, lever selected by measuring unit, and you can choose pounds, kilograms and kilograms. This function can meet the usage habits of different people. Weighing by the pound is very useful for the US Amoy Party. When you make up the order, you can weigh the goods you often buy to minimize the transshipment cost. The joystick is placed in the battery box, and the device is not displayed on the screen. This design may cause inconvenience. If many people in the family use this weighing scale, one person will change the unit of measurement, and the next person can only open the battery compartment to see the unit when using it. It is suggested that Xiaomi display the unit directly on the screen, after all, dot matrix is enough.

The cover of the battery box is made of ABS in the middle, and the production date is on both sides, 2065438+March 2005.

Third, accuracy.
Accurate measurement is the most basic requirement for electronic scales. Xiaomi publicizes that its error value is more than twice that of similar products. Let's compare it with McLaren weighing scale to test the measurement accuracy.
There is no weight at home, so we can only use dumbbells instead.

Use the Xiangshan kitchen scale with the accuracy of 0. 1g to weigh each weight in turn. The blue one is about 1 175g, the green one is about 1835g, and the last nut is about 135g, so I won't go to the picture one by one. The maximum range of Xiangshan kitchen scale is 2kg, and the red color is too heavy to measure.
A good product designed with heart, Xiaomi weighing scale evaluation report
Let's test Xiaomi weighing scale first. Code from light to heavy, put two blue and one green, and Xiaomi weighing scale will start automatically. The actual weight is 4. 178kg, showing 4. 1kg, and the error is less than 0. 1kg.
A good product designed with heart, Xiaomi weighing scale evaluation report
Adding a nut, the actual weight is 4.3 13kg, showing 4.3kg, which is quite accurate. The display accuracy of Xiaomi weighing scale is 0. 1kg. It seems that the algorithm is not rounding, but discarding a digit after the decimal point.
A good product designed with heart, Xiaomi weighing scale evaluation report
Electronic scales measure the weight of sensors near the bottom four corners. If the ground is uneven, or the weight is deviated, resulting in uneven stress on four sensors, or even one sensor is suspended, can it be measured accurately? Let's test it.
Four weights, two blue and two green, in the middle. The actual weight is 6.0 16kg, showing 6.0kg, which is still accurate.
A good product designed with heart, Xiaomi weighing scale evaluation report
Move the weight aside and the reading will not change.
A good product designed with heart, Xiaomi weighing scale evaluation report
Move the weight to a corner and the reading will remain the same.
A good product designed with heart, Xiaomi weighing scale evaluation report
It can be seen that the uneven stress of the four sensors does not affect the accuracy of the weighing scale measurement of millet, and it is not necessary to deliberately choose a flat ground when using, and the feet can accurately measure without standing in the middle, which is well received.
Let's look at Michael's performance. Here comes the problem. Put the whole dumbbell on it, Michael can't open it. I can only stand up by myself, 74.438+0 kg.
A good product designed with heart, Xiaomi weighing scale evaluation report
Plus a nut, 74.3kg, the accuracy is not bad.
A good product designed with heart, Xiaomi weighing scale evaluation report
The golden rooster is independent, weighing 74.3kg, and the uneven stress has a slight influence on the reading, which is also acceptable.
A good product designed with heart, Xiaomi weighing scale evaluation report
To sum up, the accuracy of Xiaomi and McLaren is tied, and the accuracy of the sensor is better when the force is uneven. The minimum weight of automatic start-up is about 4kg for Xiaomi, which cannot be measured by wheat. This has obvious advantages over Xiaomi. 4kg is close to the weight of a newborn baby. When measuring the baby with millet, you can put it directly on it for measurement, while when using wheat, only the parents are holding the child, and subtracting the weight of the parents may increase the error. Moreover, the curve drawn by Xiaomi's APP is directly the child's weight curve, which is convenient to compare with the standard growth curve and master the child's health status.
Fourth, Bluetooth performance.
Xiaomi and McLaren weighing scale both use Bluetooth to connect their mobile devices. Bluetooth version is 4.0, and the theoretical maximum transmission distance is 10 meter. Compared with version 2. 1, the power consumption, transmission speed and anti-interference ability are improved. Let's test the Bluetooth performance of two weighing scale models.
Test tools, LG G2, Nexus 7 II, Nokia BH-22 1 Bluetooth headset, mi band.
A good product designed with heart, Xiaomi weighing scale evaluation report
My wife measured her weight with two weighing scale models in the living room, and I stood in the dining room and synchronized the data with my mobile phone. The linear distance is close to 10 meter, and there is no shelter. Both electronic scales can synchronize data quickly, and the transmission distance is no problem. Please change the location and try again. The middle wall can be used normally, but two weighing scale models can't upload data through the partition wall.
The two of us stood on Xiaomi and Mai Kai to weigh ourselves, and the two weighing scale clung together. At the same time, we use our own equipment to receive data, all of which work normally and have qualified anti-interference ability.
Open Xiaomi Sports APP on your mobile phone, and connect mi band and Xiaomi weighing scale at the same time. The data of the two can be synchronized together, and then the Bluetooth headset is connected, so that the mobile phone can not receive the data of the bracelet and weighing scale. So is Michael. It can be seen that Bluetooth headset is better than weighing scale and bracelet in grabbing bandwidth. When listening to music with Bluetooth headset, you can't use weighing scale.
Fifth, APP evaluation.
Xiaomi weighing scale and mi band are both developed by Huami Technology, so * * * uses an APP, Xiaomi Sports.
The interface is as follows, which is relatively simple. When the main screen slides to the far right, it is the weighing scale interface.

Click the curve button in the upper left corner to view the weight curve, occupying one time coordinate every day. If it is weighed multiple times in one day, the last data shall prevail.
A good product designed with heart, Xiaomi weighing scale evaluation report
In the setting interface, you can add members, set weight goals and modify units. The units here are automatically synchronized with the settings in the weighing scale. If you change the unit in the weighing scale, it will automatically switch here, and the unit in the weight curve will switch accordingly. Xiaomi weighing scale can automatically identify different family members according to their weight, change people and weigh them, and the data will be automatically recorded in the curve of the corresponding members, which is very humanized.

In the weight goal, you can also check the comparison between your weight and the standard weight.

It also has the function of weight curve.
A good product designed with heart, Xiaomi weighing scale evaluation report
You can add multiple members, and the information is more detailed than Xiaomi's, but you can't automatically identify members. When changing people, you need to manually switch members in the APP, otherwise the data will be confused. This setting is too inconvenient for people with bad memories.

You can bind multiple devices to bind Xiaomi.

The community interface should be connected to the official forum of McLaren. You can only read posts, not post them.
A good product designed with heart, Xiaomi weighing scale evaluation report
Compared with Xiaomi, McLaren has too few functions, which can only guarantee the basic use requirements, and the APP has a long update cycle, and there is no new function after one year of use. And Xiaomi can realize more humanized application through later APP update, which is also the advantage of Xiaomi.
Abstract of intransitive verbs
Advantages:
Exquisite appearance and exquisite workmanship are unparalleled in similar products.
People with big feet will not be embarrassed to stand up.
Hidden LED screen is full of sense of science and technology, meticulous lattice, which can display a lot of information in theory and realize more kinetic energy in the future. Equipped with light sensor, it can automatically adjust the brightness of the screen.
The measurement accuracy is high, the change of 0. 1kg can be sensed, and the sensor can be accurately measured under the condition of uneven force. The minimum starting weight is 4kg, which can meet the baby's individual weighing needs and facilitate the establishment of children's growth curve.
The APP is powerful and can provide comprehensive sports management functions by combining mi band and future smart running shoes.
Disadvantages:
99 yuan, the price is more expensive than similar products. Due to the heavy weight, Xiaomi official website will be given 15 RMB, and the actual price is 1 14. MacKay bought it in JD.COM on June/October/August last year, and it only cost 58.8 yuan.
Weight 1.9kg, very oppressive, the glass surface is too smooth, and it is easy to be miserable with one hand.
Foot pads are poorly sealed and easy to accumulate dust.
It cannot be used with Bluetooth headset on the same mobile device.
Conclusion:
Xiaomi weighing scale is a well-designed product. If you don't care about its price, it's worth buying.
