🔌 Haisstronica Connectors: Efficient Heat & Quick Disconnect Solutions Review

These round plugs are very good. Multiple sizes. I use them to replace missing components to match the original wiring.

work, I'm not an electrician, I made several shrink connections with this product, which turned out to be a plus. Would buy again.

These are super cheap. Connections will bend and break if simply disconnected. Not worth the money. Absolutely avoid.

They work well for splicing wires, but the crimping area is so small it's hard to miss, especially when using a ratchet crimping tool. I suggest spending a little more money and buying Ancor plugs.

Every time I try these connectors the crimp won't hold or crimping it tighter will damage the weatherproof heat shrink. . bought them with a special crimping tool which was also complete junk

Poor crimp quality. Used a high quality ratchet crimp tool and did not improve crimp quality. The heat shrink tubing worked fine, but I'm pretty sure I'll have to replace these connectors at some point. By the way, if you don't need a detachable connection, use solder sockets.

Two thumbs up overall. I spent a lot of time looking for the best product. I have seen negative and positive reviews for this product and others. I give 4-5 stars depending on your point of view. Aside from the copper plating and built in heat shrink tubing (which is nice), they don't crimp any better than a cheap set I bought years ago.

I crimped different wire sizes using a crimping tool and Haistronica connectors. In all cases, the wires were easily pulled out of the crimped stems. I also crimped a few other better connections with a Haistronica crimping tool and they worked fine (crimping tool doesn't seem to be the problem). The crimp should be of good quality both electrically and mechanically, but Haistronica's heat shrink tubing and splices don't seem to have enough metal in the crimp barrel to be mechanically strong…
