Easy removal/install

Exactly what I needed, removal and install was easy.

Fantastic Product and Instructions

Absolutely phenomenal product and the easiest instructions I have ever read. I took the installation very slowly, and I was done in 35 minutes end to end. If I had to do it a second time, I could switch the pump out in less than 10.

I heard many reviews on other sites saying not using the removal kit was the biggest pain. Most of these people reported that it took multiple hours, and many/most gave up and bought this product with the removal kit.

At the price I paid for this, frankly I thought I was getting away with highway robbery. Especially when a new pump can give at least 5-10 years of life into a chair that you like.

Working perfectly. Directions for when you need to remove the old cylinder need to be more explicit. I called in 2 other people to help me on that step.

Saved $$$

The replacement cylinder saved me over $100. It was easy to install, well written instructions and more important does the job!! Well done, Oasis!!

Exactly what they described!

I followed all of the instructions to determine the right cylinder kit. When it arrived it took me about 20 minutes to unpack, change the cylinder and cleanup my mess. Everything went exactly as described and I am loving my chair again!
