Review: Nice, strong and secure connectors. - 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.
Review: Brilliant invention - Thes are awesome for me with my pontoon boat they are totally water proof and the solder melts the wires together I still use shrink wrap to cover them even tho you don't need to I just think it looks clean that way

### ⭐⭐⭐⭐⭐ Revolutionary
*by J***Z on December 27, 2023*

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
