Top-Notch Product.
This item was delivered today and I couldn't be happier.  I used to have one hooked up in the shower and it wasn't working quite right anymore, so I ordered one for the sink.  Was super easy to hook up and works great.  Used it on my teeth and gums and am totally satisfied with the performance.  You can adjust the pressure of the water jet by adjusting your faucet handle.  Turning the lever on the unit itself doesn't adjust the spray strength.  If you're looking for a great product, this is it.  I love these flossers that hook up to the water source - never run out of water while flossing.  That's the drawback to the tank units that I never liked.
