Mugig Zinc alloy clamp style capo is lightweight, strong and well-built. It's smooth on the hands and it allows you to play songs in different keys with limited chords. The silicone pads provide protection to the guitar neck. The spring is strong and it helps to keep the guitar in tune. Overall, this spring loaded capo is especially perfect for newbie players, but you need to be careful because it puts a lot of pressure on your strings. You should place it close to the metal line on your fret .(Note: You could get the strings to buzz a little if you put the capo on the fret bar itself, but that is not where it's supposed to be positioned!)
