I found that this showed head saves a tremendous amount of water without sacrificing the experience of a good shower.
To me; there is no difference in the quality of this shower head and of those costing significantly more.
We have had one of these shower heads for around 10 years (and just replaced the original with this one.
I was able to install it within a couple of minutes (you will want to pick up some teflon tape to insure that the threads don't leak - which is needed whenever this type of replacement is done).
Cheers!!
