Not a lot to say about a product that holds a good placement in the list of the "why didn't anybody has come up with this before?!" utility tools.........
It makes clever use of velcro stretch (thank you NASA!).
If your cabinet it's carpeted it just sticks to it, if it's not, you can still use it, provided you have an handle or something to make it hold on to.
I keep it in my gigbag so I don't have to carry a regular guitar/bass stand with me vs which I think it's much safer, since it holds the neck of your guitar/bass.
Bottom line: a very useful gizmo which is really a no brainer.
