This wasn't today but about two weeks ago (wanted to make sure I didn't have any return issues). I put together two Vyper Chairs. Then I sat in them for a little, took them apart and put them back in the boxes. I just couldn't justify the price after I put them together. The Elevated Steel Max, would have been worth it (maybe) if the casters worked a bit better (might have overtightened them a bit, but not great out of the box on both chairs) and if I could rotate without having to move the whole chair (maybe the other style adjust would have been better but wasn't available in the special edition). The Robust Steel Max on the other hand I would not get again. Didn't get low enough and with the foot ring it was too wide. Both sure were comfterble but just not worth it to me.
To Vypers credit they did take them back without issue. They were not bad at all, just not as great as I had hoped they would be. Please don't mind the messy garage that is this my current project. Hard to pull everything out in the snow so I'll have to clean strategically.
