When start use it I feel good. But suddenly stop work yesterday. I hope it can work for longer
I used to buy some slightly cheaper irrigators from other brands, but they always didn't work for three or four months. I was disappointed by this bad situation, so I decided to spend more Money, buy a brand name product and expect it to last me a little longer so I don't have to buy it again, so I ordered it on October 26th--Philips Sonicare Power Flosser 3000 Oral Irrigator, I didn't expect this brand-name product, and it also disappointed me. I just used it for 19 days, and suddenly it stopped charging yesterday. Make sure to plug it in so it has power next time I use it ,) but when I tried to use it to clean my teeth at night before going to bed, I found that it was not charging and the charging light was not on at all, so this oral irrigator didn't work As a result, I can't clean my teeth normally last night and today. Cleaning my teeth is a very important thing for me every day. I don't understand why it suddenly stops charging and doesn't work? It made me very anxious, I didn't expect this brand-name dental irrigator to let me so disappointed. This situation has me having to contact you guys to return it and write a complaint, which makes me mad because it's such a waste of my time and energy, but I need to use the oral irrigator every day. Please send in a new oral irrigator as soon as possible.我以前都是买一些价格稍微便宜的其他品牌的冲牙器,但是它们总是用三四个月就不能正常工作了,这种糟糕的情况让我很失望,所以我就下决心多花点钱,买一个名牌产品,指望它可以让我用长一些时间,就不用再用不了多长时间又得再买,所以我在10月26日就订购了——Philips Sonicare Power Flosser 3000 口腔冲洗器 ,没想到这个名牌产品,也令我失望,在我刚刚使用了十九天,昨天突然不充电了,昨天早晨我用时还挺正常,(每次用完我都确定把它插上电源,以便下次用时有电,)但是晚上睡觉前我想用它清洁牙时,发现它不充电了,充电的灯根本就不亮了,所以这个口腔冲洗器就不工作了,这样一来,昨天晚上和今天我就不能正常清洁牙齿了,清洁好牙齿对我来说是我每天非常重要事,我不明白为什么好好突然就不再充电和不工作了?弄得我很着急,没想到这个名牌冲牙器也让我这么失望。 这种情况下又让我不得不与你们联系退货和写抱怨,这让我很生气,因为这太浪费我的时间和精力了,但是我每一天都需要用口腔冲洗器。请尽快给寄来新的口腔冲洗器。

    Had to get a waterpik to clean my braces. This thing is awesome. Gets everything out, like there's a bowl of porridge in the bathroom sink after I use this thing in the morning. Battery lasts forever. Has three different jet strength settings. If you have braces and therefore some sensitivity, this is very useful. Easy to use, easy to clean, very portable, nice (and surprising) that it has USB-C charging. It's very quiet too - note that most plug-in waterpiks are super noisy like you're running a compressor... not this one. Nothing but good things to say about this unit. If you're looking for a portable waterpik device, this is the one to buy.

    Good product, but bulky so not something that I'd likely pack on travelling trips. Works really well at cleaning between the teeth. My dentist recommended me this one as an alternative to regular flossing and I love it. Only complaint is that the 15 second timer built in to let you know when to switch sides of the mouth has the water pause so you can reposition the device, but the pause is a little short. Otherwise very happy with the purchase!

    I bought this item rather than some cheaper options because of the Philips name - which I assumed would be high quality. I was wrong. The item stopped working after one month - fortunately within days of when I could return it to Amazon for free!

    On a positive note, it is the first time I used a water flosser and it was awesome in terms of cleaning and in comparison to using dental floss. Actually, no comparison. I had gum surgery for receding gums last year and I have been super diligent about flossing ever since - but find dental floss to be annoying and not very effective at the gum lines, etc. Water based flossing is awesome and this product did do a very good job of flossing, especially with the rubber based "4-way" tip.

    I believe that the negatives are related. The item is "portable" in the sense that it is battery powered and is smaller than a plug-in version of WaterPik or other items. However, the very large base to hold the water makes it ungainly to floss with. Moving the product around to reach inside my teeth was absurd. I suspect that the amount of water that ended up on the device itself because of the weird ergonomics contributed to the device failing to work after a month. The main "on" button no longer worked, which I suspect was because water had infiltrated the main button. I'm not an engineer, so I don't know what caused the device to stop working, but recharging the device had no effect. Thankfully I returned it.

    I replace the device with a WaterPik countertop flosser, which I have to plug into the wall. It takes more counter space than the Philips device and needs to be plugged into an outlet, which dictates its placement on the vanity. But so far, so good. (It was very highly rated in the NYT Wirecutter review of water flossers.)

    Love this so much. Have to floss as normal though. Use after real flossing. Lots of settings but start with the lowest one. Great for kids too. Can buy separate attachments for the whole family.

    I would recommend this product because:
    - it is a much better alternative to flossing as it requires much less time/effort
    - it cleans just as well (if not better) than traditional flossing
    - at first I was a little concerned as to if this would be painful as I have sensitive gums. I was pleasantly surprised as it didn’t hurt at all.
    A couple notes to those using it for the first time:
    - make sure the glass attachment is next to your teeth (as if you were brushing) or things get very messy
    - the product sprays water in intervals to make cleaning in sections easier. I’d recommend to keep it close to your teeth (even during the small amount of time it’s off in between intervals) to keep water from spraying everywhere
    Takes little time to get used to, I started using mine comfortably after 1-2 attempts. Highly recommend!

    I got this because my temporary dental hygienist told me it was better than flossing with actual floss. Turns out that’s not true (thanks Angela 🙄), nonetheless this product is good. I find my mouth feels cleaner after I use this. The levels are nice as well. If you have sensitive gums and bleed when you brush/floss. This would be a good product to use to adjust your gums. It gets right under the plaque and in those creases where your teeth and gums meet which keeps them clean. You can start at a lower level and works your way up to adjust your gums to the pressure.
    The battery also lasts crazy long. If im remembering right, I got it and it was fully charged and lasted three months of (almost) daily use so that was nice.
    Just remember this is not a flossing replacement!!

    I hate flossing and my dentist recommended that I try a water pic to help get my teeth clean. I tried the water-pit brand but four d them very noisy. I read a ton of reviews and many pointed to Philips being quieter than the other top contenders. I first bought a Phillips countertop model and it worked great but took up more space than I wanted. I then bought this rechargeable model and it works great. I use it each night before bed. The battery life lasts for weeks!. The water flow is as powerful as the larger units and you don't have the hose to fight. It holds enough water to do all your teeth and is very easy to fill. Like any other water flosser you have to stay over the sink and keep your mouth mostly closed and cool the excess water into the sink as you floss. You know its working when even after you brushed your teeth you see tiny particles dropping into the sink as you floss :-)
