Review on Sopoby 300PCS Heat Shrink Wire Connectors Kit - Durable Electrical Crimp Connectors For Automotive And Marine Use by Tre Boyer

These work well. I see a bunch of negative reviews about the connections slipping off after crimping. Remember. You need to heat shrink these with a heat gun. That's how they are designed to be used. I haven't had any slip off because I heat shrunk them on, as intended.My only complaint is that the case came with a broken tab, so the box doesn't close securely.
