Review pictures show a lot of melted charge ports; be careful with this one.

Had it for about 6 months it works fine, Would rather have one that had a separate water tank as I usually need to fill up again to finish. The water flow is strong enough that If it was any stronger it would cause gum tearing. Not that your supposed to spray your gums though it is for teeth but i have hit my gums before and the flow is strong.

Can't comment on this one as I do not have it, but the Bitvae that pops up at the same price has been great for me and going strong for sixteen months now. My wife is using the Coslus one that also goes on sale for $10 for six months.

If anyone out there is not water flossing do give it a try and try to get into the habit as it may save you much future pain and money. I wa lax with sting flossing as it was just a pain to do and paid a price for that. The water flossing is just easier and I am more likely to do it. I use one after every meal and snack when at home and it has saved what I have left.

Judging from the user videos it dues have a separate water tank, you either can fill it up from the access point where you open a little door on it or you can twist it in half and it separates and you fill it up that way. Same with the Bitvae that I bought, actually I never realized there was a door till I watched that video, I always twisted it in half and separated it which seems much easier From what I can gather both this one and the Bitvae are basically the same other than a lighter colored tank on this one and the layout of the buttons.

no i mean a separate water tank like a water pick a tank that holds more water then a hose to the Waterpik part. It has a tank in the handle it is just small and runs out. Did you think I had the unit for 6 months and was unable to put water in it ROFL?

Nah I just figured you didn't twist it and used the little door opening to fill it. LOl! I retired my Waterpik after I bought the Bitvae, the Waterpik took up too much counter space. I guess it all depends on the user as to how long the tank will last, I get at least a couple flossings before I have to refill mine.

I guess I am slow, I get 1/2 to 3/4 done and I have to refill. I don't just go between teeth though I go along the gumline maybe that's why

I find the same I get one one or two flossings per tank. Also retired my waterpik countertop fr both for space and as it was the much messier and harder to clean machine.

Got a different brand, but it looks almost identical. So, I would assume it's from the same factory. Anyways, I would rather recommend this use for "water gun" instead of water flosser (or "waterpik" alternative). Too strong. I wouldn't recommend this as healthcare product.
