I take back anything skeptical or bad I had to say about this style of jack. It had always been kind of a novelty until I've actually put mine to some hard use lately. I even picked up a corner of a 6.7 power stroke no problem today without skipping a beat.
Your gonna wanna put a heavier pop off valve in it, and your gonna wanna get another jack or jack stand in after 6ou initially raise your vehicle with it as it'll settle with time (probably some minor air leaks I'm not going to chase) but otherwise I've changed my tune and this thing is outstanding and would be great for your average hobbyist with a small air compressor at home. Id like to see how it holds up long term before giving it much more credit but it seems built well enough it shouldn't be an issue unless somethin tears the air bag.
