It’s game-changer
Soldering was always the messiest part of my projects, until I tried SolderStick. It's simple, it works, & it doesn't require a steady hand or a prayer. For someone who's into getting things done without the drama, this was a game-changer.

Then I found SolderStick.
Alright, picture this: me, under a car, wrestling with wires and a soldering iron that's got two settings—'cold as ice' and 'molten lava.' Then I found SolderStick. My new best friend skips the hassle, burns, and bad words. Connections are a breeze now, and I don’t miss the old iron one bit.

So easy and gratifying.
I just finished rewiring my utility trailer with these. So easy and gratifying. I've always hated crimp type butt connectors, so I would always solder my connections and cover them with heat shrink, tedious and time consuming. These take the trouble out of all that.

Gabriel

Using a heat gun they provided and it was super easy to slip it on, twist the wires and slip it back on to solder and seal in one swoop is wicked cool! Very happy! Gave them
William
Verified Buyer
Work excellent! Seal AND solder wires together! I just hit them for about 15 seconds with my heat gun till shrink tube shrunk then solder melted to wire leads...boom, done!
Brad
Verified Buyer
This solder sleeve works exactly how it is described & kills two birds with one stone of soldering wire as well as sealing the connection. It is a huge time-saver.
Kevin
Verified Buyer
After about 5 seconds the rubber material started to shrink. At about 9 seconds the solder started to melt & bond the wires. I gave the wires a firm tug & there were super tight.
