Pale and wanking Imitation

This is not the "real" capo we know it! This one has a much lower pressure on the handle, it can not support all the strings! It is therefore in the best crackling, and more generally muted strings. brief sound yucky and not change it because it is the spring itself is not strong enough!
And if not, the material used for the body of the object seems really weak! It is a kind of metal but a much lighter stuff, and brittle! I actually expected it breaks! And besides, it may explain why they do not have a better spring inside ...!
