I'll give you my opinion of the Powerbuilt product. I've been pressed in to using that brand a few times when I needed the odd tool and their standard sockets and ratchets seem to be of decent quality. Their specialty tools, and I've tried a quite a few of them out, are complete garbage.

I'd say that if you attempted to use that particular compressor on a Mercedes spring, you'd fair about as well as one would expect you would fromr playing a game of Russian roulette with an original single shot Deringer pocket pistol.

Do not, and I repeat, do not trust your life and well-being to that thing. It's what I would call a SCSO, (A spring compressor-shaped object.)
