Water flow is restricted, but there is an easy rememedy!
I received my my replacement water hose and handle for the waterpic yesterday.  It was easy to install however as many reviews stated the water pressure was restricted. Instead of removing the mounting screws simply twist off the hose and do the same with the replacement. Then push the new hose on to the waterpic mounting inlet and the pressure issue is resolved. If you compare the original mounting inlet to the provided replacement you will see the openings are much smaller on the replacement. The manufacturer could easily correct this issue.
