Review on TICONN 100 Solder Seal Wire Connectors - Waterproof & Insulated Butt Splice Terminals For Electrical Wires (100PCS) by Roger Sanders

I saw the idea of these solder shrink wraps and instantly had to buy them. Although i have to say they are not as good as I thought. The solder in the middle does not like to melt easily. I was not able to melt the solder in the middle with a lighter, so I used a small butane torch from far. Safe to say the whole shrink wrap melted before the solder did and I think its mainly an inconsistency because some work fine and others melt completely before the solder starts to melt. All in all they work decent, but rarely on the first try.
