I really hope you're talking about this and not the scorpion things...
Being a handle and not a stabilizer, it wont be good for most situations.
My friend used this for a while for skate edits and that style of filming, and it was incredible. It allows you to get into weird angles, and doesn't have the "wiggle" like the scorpion style grips have.
If you are looking to shoot super wide, super low, and get wild shots of action sports, i'd go for it. But it is in no way a glidecam or anything like it. If you are looking for something like a gimbal style stabilizer, i would look at the Opteka steadicam thing. I got one a while back, and with a quick release, it is a pretty great little tool. (obviously not glidecam quality, but 99% of it comes down to the skill level of the user)
