This a good product in as much as it clamps the strings down well and is easily adjustable for clamping pressure.
A lot fo the cheaper options have a single spring and the clamping pressure is often too high and pulls the strings sharp when fitting. With this one, you can easily adjust that. The downside to this, is that you will need to adjust it if switching guitars, which could be a pain with a room full of hecklers to contend with.
The main downside for me is that is a bit fiddly to fit and remove between songs. If you want to fit the capo and do a whole set, or use in the studio, this a great option.
For live sets where you're fitting the capo and adjusting the positioning between songs, I'd go for a different option with a trigger type release mechanism.
Possibly due to my own ineptitude, when fitting the capo it takes a bit of messing around the get it in the correct position and a trigger realease would make this a whole lot quicker.
Still a good option that does it's job well, but I'd leave this one in the case of the back up guitar or the practise room.
