So it's a 10 USD water flosser so I wasn't really expecting much however this has some key bad points:The 650ml tank is truly a shipping case in which the irrigator comes in, and it opens on both caps so when use as a tank it leaks water, and it's not just a few drops.The seal of the irrigator itself is useless, very thin silicone ring that broke before the first use so now the irrigator will fall if is not grap by the tank, it wobbles a lot.Only good thing (for some people) is that a normal oral irrigator could be too strong and feel uncomfortable if not use properly and this one is less powerful than average so less PSI means less hurt for those folks.My advice is to spend the extra 5 or 10 USD and get a normal cheap irrigator, not this really cheap one.
