If you want to save effort, you can refer to the following selection list, but be careful not to be labeled as lazy.
Ice cream cone rotator: It's fun to lick the ice cream cone while eating. If you don't want to be so "laborious", you can put the cone in the rotator and just move your mouth when eating.
Glasses cleaning machine: used to clean the cover of glasses, which saves the effort of cleaning glasses and the trouble of picking up the corners of clothes when the glasses cloth can't be found.
Use rags as slippers: Use rags as slippers and wipe the floor when walking around the house. Lazy people must choose to do housework. As for the effect, there are doubts.
Full-body hair dryer: it's too much trouble to wipe with a towel after taking a shower. At the touch of the remote control, the human hair dryer installed on the ceiling immediately sends out hot air to dry the water droplets on your body.
CD extractor: It's too tiring to take out the bought blank CD. With this machine, a blank CD can be automatically ejected at the press of a button, saving unpacking time.
Life-making driver: As the name implies, as long as the materials are put in, beautiful sushi will come out automatically.
Electronic dog: Keeping a dog requires walking and feeding the dog, which is laborious. Electronic dogs made in Japan don't need to be taken care of, and they are "pets" in the electronic age.
Electric mosquito swatter: Mosquitoes are really hard to catch. Instead of chasing mosquitoes, it is better to wait and wait for the fly swatter to catch mosquitoes.
