this Kapdoaster I use now already almost half a year with an acoustic guitar and two electric guitars, a Les Paul and a SG.
The other recessions I can not really understand, because the capo works with all of my guitars wonderful and without any problems. It clamps clean all the strings on whether the head beginning or end.
It is well made and can be mounted just fine.
I can highly recommend him each seeking a convenient and good capo and needs.
