@@maxmusclemI knows this is a really old comment here bro, but I just wanted to let you knows that I was just like you I was really skeptical and I purchased just about every single tools you can think of from pipe wrenches Plies even a sledgehammer and the only thing I really remove was the base of the chair 💺 where the wheels are never the gas cylinder itself so I was doing some research on the tables one day and I came across your video Thanks To Our Amazing And Wonderfully Lord's Help that I did bc I watched the video I purchased it and a brand new gas cylinder and I'm happy to let you know that it does work just as you described. So if anybody comes across this video and has a gas cylinder that is on a really old computer chair and you try everything to remove it purchased this tool trusted me when I tells you will never go through that again ever again.
