## Customer feedback

Customer feedback reports positive impressions of quality and functionality, including a mention of use on left-handed basses, and some buyers consider the set good value. Size feedback is mixed, although the summary says several customers found the dimensions accurate. This matters for a replacement part because slotting alone does not ensure a fit, so compare the nut against your bass before installation.
