原文:Positive: We've used these Oral-Bs for about 10 years now, like the orbital action, and have been getting good dental checkups. We ordered two of these brushes recently in separate orders, and Prime delivered one overnight, the other in the promised 2 days- typical first class service we've come t
o expect from Amazon's amazing logistics.Major drawback: "Upgraded" NiMH battery in this model takes a staggering 24 hours to charge. Predecessor's NiCad battery charged in half that time. And both last about a week & a half between charges. Other device makers have moved on to Lithium Ion batteries, which charge faster, last longer, and don't suffer from the "memory" (shortened life with age) common to NiCad and NiMH. I'm surprised Oral-B (Procter and Gamble) cheaped out on their top of the line toothbrush.The new, more compact timer displays 4 stars when you brush the full 2 minutes, but doesn't have a low battery warning like its predecessor- the charge light in the handle blinks red instead. And then you have to put the brush to bed in its charger for 24(!) hours.

译文:积极的:我们已经使用这些Oral-B大约10年了,像轨道运行一样,并且得到了很好的牙科检查。我们最近在单独的订单中订购了两个这样的刷子,一件是隔夜送达,另一件是在承诺的两天内送达的,这是我们从亚马逊惊人的物流中得到的一流服务。
主要缺点:“升级”的NiMH电池在这个模式下需要24小时充电。前一代的NiCad电池充电时间为一半。而且两者都持续约一周半的时间。其他设备制造商已经转向锂离子电池,其充电速度更快,持续时间更长,并且不会因为NiCad和NiMH常见的“记忆”(缩短寿命)而受影响。我很惊讶Oral-B(宝洁)在他们的牙刷价格便宜了一些。
当您刷新整个2分钟时,新的更紧凑的定时器将显示4颗星,但不像之前的电池警告那样低 - 手柄中的充电指示灯会闪烁红色。然后你必须把刷子放在充电器上充24小时。
