These are wonderful connectors. They function very well. After crimping them, you can heat the wrap, and they become perfect joints. They are faster to use than the original ones. They assortment of sizes is spot on.

Just received the item, seems to be of high quality. Butt connectors are organized in the container, the heat shrink is soft but not flimsy. Crimp closes well and heat shrink responds well to heat.

I recently did a couple of automotive rewiring projects and needed bulk heat shrink connectors in different sizes. This set was inexpensive for the amount you get and they worked great, providing a nice, neat, seemingly solid wire junction with just a little heat application from a heat gun. Only removing a star because the plastic box they come in is super flimsy and the lid broke off almost immediately. You will want a better container to store them in.

Product works as designed, the low met point for the heat shrink makes for quick repairs. The variety is the sell point. My only recommendation is to have a slightly more sturdy case.

These are high quality heat shrink connectors. I've gone through a couple of boxes and wouldn't hesitate to buy again. Great price as well.

Butt connectors are well made and work well.

Great value when you only need 80 or so connectors. Theyre made well and are affordable. They crimp great!
