This product promised much, and the reviews videos seemed favourable. In reality, it is cheap, unusable garbage. I tried this device on three different guitars—two acoustics and an electric. When each individual capo is actuated, it presses down too much and knocks the string out of intonation, so, retuning is necessary each time one of the six capos is actuated. The build quality is cheap and—while the instructions caution the user to ensure that the felt pads cushion the fingerboard edge—the same felt pads fell off mine on the first day! A poorly engineered design and essentially unusable live. The Schubb capos are far superior and can be quickly applied live with no retuning necessary. Very disappointed in Thomann stocking this rubbish, usually the equipment from this site has a base level of quality and is usable.
