This is a nice and effective product. Some other users have reported very short battery life. Since I have only used the product for one week, only time will tell if the internal battery serves me well or fails quickly, but I have not noticed any problems with battery life yet. Overall, I like the features of this product and it does a nice job of cleaning/flossing my teeth!
-Product includes three operating modes (normal, soft, and pulse). This pulse option has not been available on other water flossers/water picks I've had. I think it would be particularly good for those with braces to use this setting to stuff out of their teeth.
-Large on/off button is easy to activate while using the product
-Rechargeable internal battery avoids the need (and cost) to replace batteries
-Relatively large water tank. You can use it for more than once before refilling, whereas other products seem to barely make it through one use.
-The water filling cap has a very narrow opening which requires you to fill the water tank using an extremely small (low flow) stream of water. This makes the filling process time-consuming. If the opening was larger, it would eliminate this frustration and I would give it five stars instead of four. This small opening was the only real negative I had with this product.
