From The Manufacturer

Waterpik FlexNeck technology lets you simply grab and move the shower head — and it stays right where you put it. Move the shower up to add height, move it down for shorter people or children, and adjust the angle. A flexible neck of 18 inches makes it easy. Poor shower head performance is often a design issue. A great shower experience maximizes the flow of water through the shower head for a powerful spray. If your shower head suffers from low water pressure, enjoy better performance by replacing it with a Waterpik shower head. Installing a Waterpik shower head only takes minutes, and you don’t need a plumber.

Expert Reviews

What reviewers liked

Interestingly, I was amazed to find out that the shower head stays exactly where I have kept it.It doesn’t move from its position and allows me to enjoy a relaxing shower every time.Again, it includes 6 spray settings with full body power spray.I love the OptiFlow technology which allows me to get a powerful showering experience.
Much like an elephants trunk, its flexible and sprays water!... but trust me, its not an elephants trunk, instead its just a very flexible shower head that lets you move it towards you in many different directions. From both ends of the neck, this thing measures 18" inches. Whether you are short or tall, it's nice to have something that can accommodate most people.
This model can accommodate any height of shower pipes. When adjusted, the shower head will stay in any position that you place it.
Perfect for households that share a shower because of the flexible neck.

What reviewers didn't like

Due to the long 18" neck, homes with below average water pressure may not find the water output adequate with this one.
Some complaints that the shower head sticks out too far from the wall.
The 3.5 inch face is a bit small.
