Hi there,
it might be worth mentioning that the G7 Capos can be a good alternative as they are still quite small and come with an interior mechanism which allows to adjust the pressure on the strings. Additionally they are manufactured in a way to avoid scratches on the neck. After buying one of them recently, I have given away my other capos. They are more expensive than the capos presented in the video, but I would say they are worth the extra money.
Cheers Tom
