Anyone using one of those Planet Waves table-stand-things?

Thinking about one to stick between my two cabs onstage (so it'd be a couple of feet off the ground), but not sure whether they'll actually work like that (i.e. will it 'stick out' far enough to support the bass, is the grippy bit thin enough to fit in the centimetre or so between the cabs)? Anyones experiences welcome...
