## Customer feedback

Aggregate ratings skew strongly towards the top end, though a small share are at the lowest star level. Without written feedback, the figures do not show what customers liked or disliked. They cannot establish how reliably the pliers work across different link designs, so the listed compatibility and exclusions remain important when deciding whether they suit your chain.
