I've read a post here somewhere on how somebody did it without a spring compressor. That's a big risk if you ask me. The spring holds up the car - imagine the energy stored if something were to go terribly wrong and the spring released all that energy on your body.

I bought a used Klann on eBay and and have used it a lot, maybe 10 or 15 times already (my cars and other's Benzes). Very well made tool, and I feel completely safe using it. I think somebody here rents them out.
