Not bad, be careful of positioning on chest though.

Wanted one of these ever since seeing Arnie use one at Golds. While it does isolate your bis nicely, it did take a lot of adjusting as it tends to compress against your chest quite heavily when curling and I found it inhibited my breathing quite a bit if you get it in the wrong spot which is not quite what I was expecting. The strap and mounts also appear to be of pretty poor quality, just a cheap rivet and flimsy material, not sure how long they'd last with regular use.
It's probably more of a marketing gimmick by Golds taking advantage of Arnie's fame rather than a genuinely useful gym accessory.
I still use it, it's more of a novelty though than something I'll be incorporating on a regular basis - think I prefer preacher curls on a bench which are just as effective for isolation, each to their own though.
