[Expired]Waterpik Cordless Advanced 2.0 Water Flosser

: Saw the $49.99 discount notification last night and placed an order. It shipped at 2 AM and was delivered by 7 AM—since when did Amazon get so hyper-competitive??? 昨天晚上看到49.99折扣推送下单，半夜2点发货，早上7点delivered，亚麻什么时候这么卷了？？？

: Can this actually clean teeth thoroughly? 这个可以把牙齿弄干净吗？

: I don't find it useful, regular dental floss is the only thing that can clean thoroughly. 我怎么觉得不好用呢，还是一般的牙线才能清理干净

: Is it good to use? 好用吗

: Are these just different colors? 这几个就是颜色不一样吗

: I bought this brand at Costco, and it broke after only two uses when I traveled. But I've had it for a year, so I probably can't return it. 在Costco买的这个牌子只有出去旅行的时候才用了两次就坏了但是买了有一年了应该也不能退了
