Query: Works great on my Gibson

Bought this and the Kyser capo for my acoustic Gibson L-140 with the understanding that some reviews say it does not work on all guitars. All I can say is it works great on mine. I like the low profile of it, very unobtrusive. Also like the variable tension. It is made of plastic so I can't say how long it will last but at the price, it's a very good deal.Only problem (if it IS a problem) is that unlike the Kyeser, when not in use, you can't really stick it on your guitar's peg head out of the way. No biggy at home, but when I am a world famous touring rock star, it may prove inconvenient.
