Water everywhere...
The one thing that will get cleaned from using this, or probably any water pick, is your bathroom.  Have lots of paper towels or cleaning cloths at hand, because the spray gets EVERYWHERE!  You'll spend a good 5-10 minutes wiping and drying your bathroom and yourself when you're done, each time, every time.  The problem with water picks is that at the dentist, you are reclined or laying flat when they use it...so the water is collected at the back of your mouth and also suctioned out.  That is NOT going to be the same thing in your house.  From the moment you turn on the pick, it's like a llama spitting in your face and mouth.  Be prepared.  The ONLY reasonable place to use this as commercially bought, is in the shower.  I'm not going to return it, because it's not the actual product's flaw, it's all h2O picks... then again, maybe I would.
