I have used some superior trigger capos like nordic... And I must say that this capo has a build quality comparable to them... It feels very solid to hold... Is fully metallic... Spring is good until now... Looks like it will last... And the padding is good too... No buzzing sound... And also the grooves from strings can be easily removed by rubbing the rubber pad a little... Ensures no buzzing during next use... i will recommend you but it... This type of quality in this price is really astounding...
