I used one a while back at Nicks day - the last time Bovvy was used in fact.
One of only two jacks that I have found that would actually go under my car, and it almost gets under even when I have a flat.
Unfortunately I got a Snap-on one as its lower, fractionally cheaper (if ya know the right people ), has a lifetime guarantee and mainly cos I needed one immediately.
Thats taking nothing away from these though - they look and feel top notch.
