Best for $20
It is a simple machine, you turn it on, there's five modes and a few nozzles for different uses. For such a low price point, I cannot recommend this more if you are just looking for a cheap way to water-pick clean your teeth. I'm not really sure why some people are complaining about the water pouring out of your mouth, since that's what water does. The only complaints for me are that the power is far too strong for use on your gums or back of throat, and that the tank is pretty small and hard to wash. However, for $20, you simply can't beat it.
