    • Nice, strong and secure connectors.
Number of Items: 400
These heat activated solder shrink connectors work well, making secure butt connections. Please note that the proper amount of heat must be applied to activate/melt the solder. A heat gun is essential to properly use these connectors. Please also be aware hair dryer should not be used as a heating device, as it will not provide sufficient heat to melt the encapsulated solder. Once cooled, the connection is permanent and quite strong. I highly recommend these connectors. ... show more

    • Revolutionary

These are incredible. I have used these now for multiple applications, from a car to sprinkler wires to vending machines. Just carry a heat gun and short extension cord for most places and you're set. You do strip the wires farther than you usually would with a crimp. The only thing I will say somewhat as a warning is that they work way better with stranded wire than solid wire. I have had a couple instances where solid wire pokes a hole in the coupler and I have to start over. Other than that, these are easy to use, guarantee a solid connection, go waterproof, and make it so that the connection isn't a massive piece of plastic that you will be able to see even under shrinkwrap. If you cover the wire with shrinkwrap afterwards, you won't even notice that there is a splice in the wire ... show more

    • Great wire connectors that are easy to use, and give a solid waterproof connection.
Number of Items: 400
What I like about this kit is that it is huge and has all the connectors I will ever need. They are easy to use, right out of the box although I got several ones that were in the wrong spot. Probably due to rough handling during shipping. They are a solid connection and seem to hold up in the water well. YOU will need to buy a heat gun with a flat tip to make these work better. It just makes the whole job easier. ... show more

    • Love these things. Never solder again.
Number of Items: 400
These things are so cool. Best consistent butt connection I've ever been able to make. I use a heat gun with the narrow tip. You can burn through them if you're not careful. There is a fine line between hot enough to melt the solder ring and not melt the heat shrink. Once you get the hang of it you can do it every time. I lost his the little colored ring grips the wire too. You can kinda hit that part first to help hold the wire then hold it on the solder ring. I always do another layer of heat shrink just in case I burn through the one it's made of. I will definitely buy more of these. I hope they have different types of connectors in this same style. I do a lot of diy vehicle electrical work, these are my favorite now ... show more

    • Great option for 1 wire to 1 wire splicing.
Number of Items: 400
I used the cordless DeWalt heat gun on high....say about 2" away from the splices. Forgot to use a reflector. Didn't burn or brown.....does take a good 30+ seconds to get the solder to melt. Mainly focus on the solder, and not the shrink tubing. The blue ones worked fine. When I was using one to one wire. But when I had to do 2 to 1 and used the large yellow...each one split....on the doubled up side. So I don't think they can handle uneven splices. Additionally. . when they split, the soldier is not "pushed" into the wore, so the soldier just pools up on the outside and doesn't bond. I didn't dock a star for this, as they work well....just not in this way (2 to 1 splice.....which the instructions don't even mention) ... show more

They suck, the solder won't hardly heat up and actually solder. I pulled four splices apart. First time I bought the Haisstronica brand and they were decent. I tried these from reading the reviews and thought may be better quality. There not! You don't use them every day so I missed the return window. Regardless buy another brand they suck! ... show more
