It's true, but the quality is different, some are expensive and some are cheap. I believe it's better to be more expensive. The main difference is that the glass thickness of the cup is different, and the mass revolution of the motor is different. If you just want to try it out early, you can buy a 3400 model. If you use hard things for a long time, you can buy something a little more expensive, 7800 yuan. Now the price in the high-speed mixer has dropped a lot compared with the beginning, and it is still quite easy to use on the whole. I hope this helps.
