Electric toothbrushes are not popular in China. After all, compared with disposable toothbrushes, the initial cost is too high, and overseas shopping may be a good solution. This Oral-B Smartseries 5000 is the flagship model of Oral-B, and its scientific 3D plot mode can use the 3D vibration rotation of 40000 times/minute before and after vibration+8800 times/minute. Even if you practice hard, you can't reach this level!

Oral-B Smartseries 5000 is currently quoted at $77.99. After using the coupon, the actual payment is $70.99, which is about 430 yuan. The price is 550 yuan. Taobao's same price is 1400 yuan, so the price advantage is obvious.
