I really like my capo, the blue looks good with my light natural finish accoustic, and it works as it should. However, I feel like it deserves 4 stars simply because it could be a much more robust product. For example, I think the bottom part of the clamp should be a little longer, and rounded (the back side of a guitar neck is rounded, after all). The spring could definitely be tighter...I do rarely notice buzz from not quite being tight enough. Also, the design is fairly nice, but it's mostly aesthetic...it's not really super comfortable and easy to move around necessarily.
