Not wanting any broken face parts from springs slipping I searched for a different design and found these on ebay. They looked very chinese in quality from the pics but solid and with 3 different pairs of "jaws". They arrived within a week and the pics don't show how massive this set is. Try about 15kg all up and the biggest jaws could compress truck springs

Today I tried them out for the first time and I'm glad I spent the money and went with these. They work perfectly, effortlessly compressing L series front and Vortex rear springs with absolutely no chance of the spring slipping out. The jaws have a little tab in the back to retain the spring in its proper position which means when the springs is under compression it is impossible for it to slip out of the seat of the jaw. The spring is compressed square and even with no bulge, with very little effort required to turn the screw with a 22mm socket. Half the time you can't even tell if you're compressing the spring or not.
My only complaint is the assembly is quite hard to handle without a big vice to clamp it in. It's very heavy, always trying to roll away or fall over, you have to hold the strut/spring with one hand while you turn the screw with the other. I've already come up with a method of bolting it to the wall with brackets, which would make changing struts a joy.
I rate these 5 out of 5

The gold jaws are almost too big for Vortex rear springs but still work well. The black jaws are perfect for L series/MY front springs. And the silver jaws are uselessly massive, unless you have a land yacht, monster truck or road train.
