A great product that works as it claims. I have only 1 concern, it does little to brighten the tone of my strings, it could be my strings too, to be fair, but I have tried it on different brands of strings and the brightness is minimal. As stated, you DO need to use it before and after playing. Also helps keep callouses from cracking on your finger tips. It is still a great product that will make you play faster.
