Review: Perfect for Vertagear gaming chairs. - Bought this to replace the piston in my aging Vertagear gaming chair. Perfect replacement. Gives the same lowest level with an extra 1inch/2.5cm of height. Easy to fit, well packaged and seems to work really well. Only time will tell on its longevity. TOP TIP: Be aware that there are varying low and height differences so be sure to measure your existing pistons lowest, highest, overall length and travel length. It's also a good idea to check the taper at the bottom of your existing pistons as not all pistons are equal in this area. This one sticks through the bottom quite a bit so if your wheel base is low to the ground it will probably hit the floor before the wheels. In that case go for one with less of a taper so not so much of the piston sticks out the bottom of your wheel base.
Review: Good value cylinder which fitted the Corsair T3 Rush - MASTERY MART 9 Inches to 13 Inches Gas Lift Cylinder for Most Office Chair, Fitted a Corsair T3 rush gaming chair which the cylinder failed. I believe the Corsair chair has had two replacements cylinders with the last one lasting around 6 months before failing spectacularly. This fitted the gaming chair perfectly and is a good replacement. I'm hoping this last far more than 6 months so will update the review if anything happens. Installing the cylinder was easy enough i couldn't salvage the base plate due to the damage so i also had to replace the tilt plate and base with the wheel. Overall This so far is good and fitted perfectly well, good value comparing to the original which in my opinion fails fairly quickly and the person isn't at all heavy.
