200PCS Solder Seal Wire Connectors - Sopoby Heat Shrink Solder Butt Connectors - Waterproof Solder Connector Kit Insulated Automotive Electrical Wire Terminals

Great quality and nice variety of sizes. I bought these to have them on hand for when I need them which when you are living and travelling full time in a 5th wheel is pretty much anytime something stops working it seems everything is somehow tied to electrical in one of these and because it's like a earthquake in the trailer every time you move it things break and come loose fairly often. I've used several of these already and love having them onboard because every time I've used one the outcome has been perfect the melt exactly like they should using my 1500 watt hot air gun all you have to do is strip and short piece of each wire end your using first insert one wire end into the splice and melt the splice onto the wire, insert the other wire end into the open end of the splice and again melt the splice with a hot air gun or other heat source the metal center of the splice will complete the circuit making the wire whole again that's it it's not hard at all. I've had great success with these in the trailer and in my pickup I use to tow the 5th wheel I don't see running out of these anytime soon but when and if I do I will be buying more just like these from this seller.

Good product but grossly overpriced

I read a bunch of the reviews and took a chance that this lived up to the hype and it really does. It was super easy to join all the wires in the cable harness that I was working with. I was easily able to push the one wire through and then the other from the other side, have them mingle in the center and then hold it over my upright heat gun and just watch the heat shrink tubing and then the solder seal up the joint. It was beautiful and made a strong and water tight seal (not that water tight was really anything I needed to worry about), just like a regular soldered joint and heat shrink, but without a two step process. The only thing I needed to be careful of is that the whole thing is still a bit gooey when you take it away from the heat gun, so letting it cool a few seconds before applying any accidental lateral pressure kept from making a mess. Connected about 30 pairs of wires in about 30 minutes without having my hand hurting from crimping connectors over and over again. Love this, would totally order it again, and as some others mentioned, the box was surprising small and compact. Really great, highly recommend, but you definitely want to have a heat gun.

Aun con pistola de calor al maximo la soldadura no se derritió. Solo el plastico se encogió, nada mas.
