I don't have one but looking at the specifications of their website I can't say I'm all that impressed.
Apparently it screws into a singl bank stick, so stability has to be suspect, not to forget wither that sometimes its difficult/impossible to get a bank stick into hard ground or the concrete on many commercials.
Personally, when fishing commercials I use a second set of pole rests on the legs of my Preston box and that works very well indeed; safe and secure too.
When fishing more 'natural' lakes for Carp I simply use a pair of bank sticks with a wide rod rest on the front one and the usual thinner one on the rear.
