Rovan Roll Cage... Anyone?

[REDdawn6]

Hey guys. My son wants to buy this roll cage.: http://m.ebay.com/itm/331168336749

He keeps asking me but I have no idea if it is strong enough. Anyone used one of these? I know about Kraken, TC, etc.... Thanks

I'm interested in the cage myself with out the panels, and use it on my T1000 to help prolong the body from roll over damage.
