Very good.
I am an actual purchaser of this product and my review is genuine. The water pick is well made and works well.  I attached it to the bathroom sink by removing the aerator with a pair of pliers.  Then installed the water diverter by hand.  Attached the holder assembly to the wall with adhesive.<br />It works flawlessly and no leaks.  The water pressure is good, but not as strong as the  electric motorized water picks I own.  But does a decent job of cleaning my mouth. I recommend this product. Happy with purchase.<br /><br />pros:  no need for electricity.<br />  no need to keep filling the water container.<br />  well made. no leaks in connections.<br />cons:  some people might feel the water pressure is no strong as an electric motorized unit.<br />  not as portable as an electric unit.
