LOVE IT!
Ok, so its only been installed one day, but I love it! I thought nothing could fix our horrid water pressure, but I was willing to try for . Best spent ever! That shower has gone from pathetic to the best pressure in the house and I am one happy camper.

AAAHHHHHHHHH
I have been putting up with relatively low water pressure for several years in my upstairs showers. I tried different shower heads but was always disappointed with the results. Next I investigated different solutions and found them to be way too much to invest for a "Hotel" shower experience.
Then I stumbled on this Delta water amplifying shower head and have found it to be well worth it. Initially I purchased only one to test it out, but after a couple of weeks decided to get another one for the other bathroom.
My children, with long hair and longer showers love the way this works! The pressure is not too hard, but a significant improvement!! Have not had them long enough to vouch for the reduction in the amount of water used, but will trust that the manufacturer knows what they are claiming.
Even if they were wrong and my water usage stays the same or goes up a little, it is well worth the risk.

Amazing Pressure From A Low Flow Showerhead
We replaced our showerhead about 10 years ago with a low flow model. The performance was not great but at least we were saving water. Technology has improved in the time since, so I replaced it with this model from Delta. It's amazing how great this showerhead is. It is possible to adjust the pressure. We keep ours set at about 50% because full pressure is actually too much. We are very happy with this model.

It more than adequate on low flow setting
We bought a second one, after trying out a first one. On "high" flow setting, it's too much water and pressure. So, it's set on "low" all the time. It's simply awesome. Why pay more or buy anything else? Really.

lives up to its description
This lives up to its description. While it is not as hard a spray as the speakman shower head (which I use in our fitness club), it is quite acceptable.
