This is very quick in gauging positioning of the reed on Mouthpiece.

I will definitely recommend this product to others

I've not really used it but it seems to be a nicely made bit of kit. I get the principle but I fail to see the value in using it really. I just fit my reeds to where I need them and blow them in. If the lay curves on your mouthpiece rails are off then there's not much you can do about that really other than to buy a new one or try to find someone who can work on you mouthpiece at great expense.

Just that - it helps with identifying where a reed needs work. Expensive enough for what it is but if you're going to spend €80 on a Black Diamond Reed Geek it's probably worth shelling out another €20 on this.
