[Expired]Philips Sonicare 4100 Plaque Control Rechargeable Electric Toothbrush

: One brush head. 一个刷头

回复 @匿名用户 : Bought the new version today, compared to the old version the toothbrush size has shrunk a lot, and it seems the vibration is much weaker... 今天买了新版，跟旧版比牙刷大小缩水了很多，感觉震动也弱了很多……

回复 @匿名用户 : The vibration amplitude of this toothbrush is too small, and the material is insufficient. If the gears inside break after a year of use, would you be okay with that? 这个牙刷的震动幅度也小了，用料不足如果用一年以后他里面齿轮断了，你可以接受吗？

: Is it any good? 好用吗
