After seeing the ad on tv I purchased one. It's easy to install (once you get your old shower head off) as it simply screws on without the need for that pesky teflon tape. There are 100 holes which provide a slightly more then gentle spray which is very wide. Uses 2.5 gallons a minute (quite low). You can push a button to get a more concentrated and "tingly" spray as well. A very good product - and it looks nice too.
