Performs exactly as advertised. The first capo I had was a screw on and was a pain in the but, worked alright but with a significant amount of time to adjust. The second was a pistol grip style with a very small string. Easy to adjust but didn't have enough pressure to completely eliminate string buzz. This capo is solidly constructed and applies considerable pressure which is what is needed when capoing higher up the neck. Solidly constructed well product that works flawlessly.
