I purchased one when they first came out. I'm not sure if they fixed certain quirks since then. If you have a Roto-Start, you'll have to grind a notch in the rear bracket to work. The cage isn't wide enough to fit a New Era tank guard, so you'll have to grind the tank guard in order to fit (I have billet TVP's so that might account for not enough room) . It's probably a problem with most roll cages, the brackets that hold them on bend when taking a direct hit on the cage. Now these are pretty good size hits though, probably 10+ foot drops on the front or rear of the cage. They do take a beating but I stopped using mine since the brackets were so badly bent. Good luck.
