Ergoplay Professional

This is a great product and I love it but it does not work on guitars with open grain sides. They do supply stickers to apply to the sides of your open gained guitar and this is supposed to give the suckers a smooth surface to stick to but they do not work. There is still enough undulations on the surface to mean that the suckers fall off after a very short time. I'm getting a solid one for my open gained guitar and hope that works but this product is not suitable.

Bought this to get more comfortable support rather than using a foot pedal. It rests comfortably on my lap and I generally don't have any major issues with it other than that the suction cups come off quite frequently. Usually the position of the cups themselves are enough to support the body anyway, but if you move too violently it *will* fall off.

To sum it up: Does exactly what I want it to in a sufficient way, but I reckon it would be too unstable to use for professional performance.

The support is comfortable, but it slides a little on the leg, my teacher uses one, but I'm uncomfortable.

I am not sure if it is indented for professionals but for the average guitar player is more than enough. It is more convenient than a foot stand (your back will thank you) and offers a better position overall. Just make sure the suction cups adjust properly or else they will go off with too much force.
