Leaks no matter what I do
I should have listened to the other reviewers who said it leaks. Ok, I read the instructions BEFORE I installed it. Not much to read... mostly pictures. The instructions say not to use teflon tape... I think. The way the instructions are written it is hard for me to tell if they mean no tape on all showerhead models or only the fixed showerhead models. But, I can't see why that would matter. Either way: 1) I tried it without tape and hand tightened, and it leaked; 2) tried to tighten it with pliers, still leaked (worse); 3) took the vacuum breaker off and it still leaked (in two places now); put the vaccum breaker back on and put tephlon tape on the male threads and hand tightened, it leaked; 4) left tape on and tightened with pliers, you guessed it... it leaked. Should be rated at 3.5 GPM -- 2.5 GPM through the showerhead and 1.0 GPM down the wall.

Reasonable handheld shower for the price
Purchased this unit to pair with a fixed wide patter showerhead for walk in shower. Wanted a hand held option for cleaning, as well as massage options. The water pressure is adequate but not strong, even upon removing the flow restrictor. The massage action is OK, but not as strong as my original shower masssager from the mid 1980's.
The vinyl hose is annoying as another reviewer mentioned, in tat it does not hang well and can result in shower head twisting while using it.

DON'T BUY THIS ITEM
The spinning face, which selects the mode and sprays water has come loose. Water leaks all around the head and thus, has lost all pressure. I'm pretty sure this item will be replaced by Waterpik; however, what am I suppose to do while I wait for Waterpik to deal with this? If there isn't a replacement, I'll update this review.

Waterpik
Good product for the price. One thing that should be made stronger is the piece that gets screwed into the wall pipe - it is weak and very wrench-unfriendly

Easy to install, but not as powerful as I expected...
Good price. I didn't like that its made of metal looking plastic, wish it was made of a sturdy metal, but I guess you get what you pay for. Easy to install, and nice long cord, however it's stream is very weak. My shower has incredible water pressure, so I know its not my shower, my old shower head was like a fire hose power blaster, so I was looking for something a little more gentle as to not blast my face off, but this is pretty weak, even the stronger settings don't get all the soap out of my hair as quickly as I'd like. If you prefer a more gentle pressure, then this shower head may work out for you, but if your looking for something more powerful, I'd shop around a bit more and maybe spend the extra dollar.
