Review (4/5): Good so far
I am one of those who prefer water flossers to string-based flossing. Process is much cleaner and, in my view, cleaning is more thorough.
This Chinese designed and made unit works well. You fill it with warm water, select the mode, possibly select a specific pick - but I always use the regular one - and you start flossing away.
Item design and ergonomics are generally Okay. However, the manual is not exactly helpful but most of us should be able to figure it out, eventually. Charging is via a custom USB cable but there is no actual charging unit so you need to find one such as your phone charger. You only need to charge it once every couple of weeks if you use it once daily.
Overall, a useful item and it does appear to be durable. Time will tell.
