原文： ORIGINAL REVIEW (five stars)
I'm new to water flossing, but traditional (string) flossing has become more problematic for me, so I wanted to check this out. Turns out it works as well as traditional (string) floss. My initial web searches had all pulled up "research" that sounded more l
ike ads for water flossers, but I finally found some NIH articles showing that it does, in fact, work better than string flossing (search for the phrase: NIH water string flossing). So I got this unit myself and was surprised to find first-hand that it works as well and perhaps better than traditional floss--my mouth felt cleaner than it usually does after flossing, and when I followed up with string flossing (to see if it would get anything the water flosser hadn't), all was clear.
PROS
* Works better than traditional string floss - leaves your teeth cleaner
* Has different strength settings so you can adjust
* Comes with multiple tips. Most of the ones with brushes say they'll need replacing after 3-6 months, but the one that's just a clear plastic tube seems like it will last longer
* Battery charger is magnetic - you set the unit down on the counter, plug in the charger, and then magnetically attach the charger to the front of the unit (I tried attaching it backwards or too high / too low, and it just realigns itself to be correct, so it's super easy)
CONS
* It's quite big - maybe 10 inches tall and 4 inches at the base (while string floss is teeny tiny), though fortunately it's easy to hold and not heavy
* Has a learning curve (probably less of one than string floss, but most of us already know how to string floss)... nothing bad, but it takes a while for it to become a _habit_ to not turn it on outside your mouth (which just shoots water across the room, as you'd expect, and is easy enough to clean up)
NEUTRAL
* You may have to fill the water reservoir at the bottom a few times during flossing... but this is easy to do, and I'm glad they didn't just make the unit even bigger than it already is
* The instructions say you can use the unit in the shower, which would be nice to keep down the mess while you're getting through the learning curve, but I don't like the logistics of refilling the empty reservoir while showering
***************
UPDATE: three months later, the battery is failing even though I leave this plugged in all the time (except when using it). The battery can no longer make it through a single flossing so I have to switch back to manual floss partway through. In doing so, I found that even though most of the time my mouth feels cleaner with water floss (vs. traditional string floss), there **were** a few pockets where normal flossing again made my gums bleed (a sign that the water floss wasn't getting in there well enough). So I'd suggest that you continue to string-floss on occasion for those benefits. Lowering rating to just 3 stars out of 5 because there's no excuse for a battery failing to hold a charge after just 3 months; otherwise I'd probably do 4 stars.
***************
UPDATE 2: After another 3 months of just flossing 1/2 my mouth with water (when battery would die) and then switching to string floss, I finally got around to calling customer service. I wish I had done it sooner! Within 15 minutes they had a new unit on its way to me. I did have to read them my serial number to confirm the purchase, and I'm mailing the old one back (so they can test and see how/why/where it failed). But my new one is now in hand and working well so far. Raising to 4 stars because I don't yet know if this one will last, and also because I do still need to string floss on occasion. But overall I'm happy again.

译文： 我是第一次听说水牙线，但对我来说传统的牙线也存在问题。所以我想尝试一下水牙线。事实证明它和传统的牙线一样有效。我一开始在进行网络搜索的时候就已经找到了“研究”的字样，听起来更像是水牙线的广告，但我还是发现了一些国家卫生研究院的文章，事实表明它确实比用牙线清洁牙齿更有效(搜索这个短语:NIH的水牙线)。所以我自己找到了这个物品的时候，我很惊讶地发现，它的效果和传统的牙线一样好，甚至更好，（跟传统牙线相比，我感觉洁牙后我的口腔更干净）。而且当我用牙线清洁牙齿时（看看它是否产生水牙线不该有的东西），结果什么都没有，一切都很干净。
优点：
*效果比传统的牙线更好，可以使你的牙齿更干净
*你可以对力度大小进行设置，对力度进行调节
*拥有许多技能。大多数使用刷子的人说他们需要在3-6个月后更换，但那只是一个透明塑胶管，似乎可以使用更长时间。
*电池充电器是磁性的，你可以设置计数器，插入充电器，然后将充电器固定在前端。(我试着把它倒过来或放在高（低）的位子，它只是对自己重新调整，所以它非常容易使用。)
缺点：
*它大概有10英寸高，底座4英寸宽 (而牙线是很小的)，尽管令人庆幸的是它很容易握着，也不是很重。
*使用牙线本身有一个学习的过程(但我们大多数人已经知道如何使用牙线了)…没什么不好的，但拿出嘴巴的时候要养成一种习惯，这需要一段时间，(正如你所期望的那样，它只是嘴巴里射水，而且很容易清洗牙齿)。
中立：
*在使用牙线的时候，你可能需要在底部填满水。但这很容易做到，我很高兴他们没有在底座本来就很大的基础上让它变得更大。
*说明书上说，你可以在淋浴时使用牙线，以便你在学习过程中，可以较好地避免这种混乱状态，但是我不喜欢在淋浴时进行水量填充。
***************
更新:尽管我一直把电源插在电源插座上，但3个月后电池还是没电(除了使用它)。电池电量不能再支撑进行一次牙线清洁，所以我必须换回手动的牙线。在这样做的过程中，我发现即使大部分时间我的嘴都感觉干净了（跟传统的牙线相比），也有时候正常的牙线也会让我的牙龈出血(这表明牙线还不够好)。因此，因为有这几点优点，我还是建议你继续用牙线清洁牙齿。一共五颗星而我只打了三颗星，这是因为没有理由让电池在充了三个月的电后还是没电;不然的话，我可能会评价4颗星星。
***************
更新2：在我多次使用牙线清洁到一半的时候出现了电池没电的情况，过了3个月后，我终于打电话给客服了。我真希望我能早点这样做！不到15分钟，他们就给我寄了一个新的牙线。我必须给他们看我的序列号以确认购买，然后我把旧的寄给他们(这样他们就可以测试哪里坏掉了)。但我的新牙线已经到手了，而且工作得很好。给了四颗星是因为我还不知道这一种状况是否会持续，而且我还需要不时地卸下牙线。但总的来说，我很高兴。
