## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great, if it fits
*by M***E on September 4, 2023*

I installed this clamp on my magnificent used 20 year old Steelcase Citation desk chair. Unfortunately, the clamp was not quite big enough to fit the shaft on the Citation gas cylinder, which is 1.25". Making it fit took all afternoon and a trip to the hardware store, but the end result is excellent. After fussing for an eternity trying to to do the impossible with supplied cap screws that were just a hair too short. In the struggle, I stripped the threads on one side of the clamp. Doing what I should have done an hour earlier, I retreated to Ace Hardware and bought longer screws, flat washers, and hex nuts. I had to drill out the stripped threaded holes in the clamp, put in the longer cap screws with washers and hex nuts, slipped the clamp to the right place on the shaft and tightened it down. Tight. My chair is now at perfect height and no longer sinks.You may ask why I gave a device that was difficult to make work a 5 star review. It deserves 5 stars because it would have been quick and easy if the gas cylinder shaft had been the size the clamp was intended for. The design and quality was good. If it had not been, my fix would have been impossible. If you know your way around things and tools, the product is great. If the clamp fits out of the bag, you should have no trouble even if you are not a tools and things person. If the product were a piece of crap, like so many are, I would not be sitting comfortably typing this review.

### ⭐ Does not work
*by A***I on June 29, 2023*

Installed it correctly, I weigh 119 pounds, chair STILL sinks when I sit in it. This device slows the sinking down at best.

### ⭐⭐⭐⭐⭐ Simple, effective, and inexpensive
*by W***R on August 26, 2024*

I have had office chairs for many years. At some point, all the pistons fail not matter how expensive the chair. I have tried many fixes and the most effective, until today, was a short piece of PVC. But this clamp is $6, is screws together in 2 minutes, and my chair is no longer sinking. I am very pleased with this simple, effective, and inexpensive fix.
