Tried some for the first time the other day. Didn't think it stunk too bad, but not good by any means, and one wiff did choke me up a bit. Much oilyer than Hoppes, my usual go to. Didn't seem to cut carbon as fast as Hoppes, and I don't mind the smell of Hoppes at all, so I guess I'm not changing. I also like non-chlorinated brake cleaner for hosing out actions, trigger groups, etc. Got to be be sure to oil well afterwards though.
