Great product
This flosser does a great job. It is easy to hold, and has good power to clean out between tight-fitting teeth. It is easy to fill, empty, and recharge. I thought it would be difficult to use, but it fits my hand just fine and is light when full of water. I still spray water around, but it is so much easier to use than my larger countertop flosser. I am flossing much more often than I did before I bought this item. It holds enough water. My gums feel great, and I haven't even gotten out of child mode yet. I wish I had bought this sooner.

Works great!
Works exactly as expected. The pressure is strong but comfortable and it cleans much better than regular floss. Easy to refill and charge. Definitely worth it for the price.

Good addition to your teeth cleaning regimine.
Works well. I don't know how much of a difference it makes. I use it after every time I brush though because I hate plaque buildup on my teeth. Does not replace actual flossing. So, I brush, then floss, then use this to wash everything away. Seems ok. Don't know if I recommend, but it's a good value for the price. Not too loud, plenty of water capacity and I do like the rechargeable aspect of it. I've had it for about 2 years I think now, so yeah, it's holding up well for something that gets used at least 3 times a day.

Really awesome oral dental Flosser!
This Dental Flosser is easily equal to any of the more expensive brands. It works really well, and holds a charge forever. I brought it with me on a two week vacation and it is still going strong, not needing a recharge. Great accessories as well.

Great pricing and easy to use.
It is very comfortable to hold and use. My teeth felt very clean after I used it. It feels very sturdy. Easy to add the water. My only concern is the plug receptacle: there is a tiny rubber plug to cover it. It is not permanently attached, so be very careful not to lose when you are charging the unit as it is needed so no water gets in. Love that it is not umbilicaled to a large unit making it hard to have the mobility needed to do a thorough job. It is very comfortable to use. It’s sleek and nice looking. I don’t mind the buzz, and I find the pressure is very good. I did need to reload the water, but I did on my old one too. Very good price point for what seems real quality materials.

Lasted 11 months, which aint bad for what it is! Wait! there's an UPDATE!!
Gonna give it 4 stars. Got mine 11 months ago almost to the day. Just 2 nights ago, seems like the battery is conking out. Just losing the pressure it once had. Worked GREAT the time it was working, so it was worth the $$ for sure. But now time for a new one. Will shop around and experiment with a different brand. !!UPDATE!! OOPS!! I accidentally hit the mode button! Used it again tonight, and it was back to full power. I guess my big fingers hit the button while I was using it. I don't know why I didn't think to check that for two whole days, but no, this thing's working great! Review back to 5 stars!

Really nice for the price
Love this thing. Been using it for a long time. Dentist says that my hygiene is good. So this must be working decently well in my routine. Holds a decent amount of water. I usually will fill it up twice per use. Rechargeable battery life is pretty decent.

Doesn’t hold a charge, but replacement is coming!
I’ve only had this for four months, and all of a sudden, it just won’t hold a charge. It stopped in the middle of using it yesterday. While it had been holding a charge for a couple of weeks, I had just charged it a few days ago. So I let it charge overnight, but it didn’t even make it halfway through the tank the next morning. It can’t even get through a single use now. Fortunately, I got this on sale because it would absolutely not be worth the money at full price. Battery issue aside, it’s decent for its size and mobility. There isn’t a lot of control over water pressure, but it gets the job done. Edited to add: After reaching out to the manufacturer, I received an immediate response. After asking a quick clarifying question, they are sending me a replacement completely free of charge. So, at least their customer service is excellent, and therefore deserves a bump to 3 stars. I will update this review if the replacement works for a longer period of time than the first one.

I always find it difficult to use the string type of Dental Flosser as my teeth are too close together and it bleeds when I forced the string between the teeth. With a Water Dental Flosser, I don't have any problem as the water jet is strong enough to flush in between the teeth. I need to do this as my gums are quite sensitive and get inflamed if food are stuck in between the teeth which toothbrushes cannot get it out.
