This is a great set of heat shrink with solder connectors.
I have already used half of the red band ones with great success. Not a single failure, except for a burnt finger ; - )
For anyone wondering, the hot air gun got me instead of the connector. So be careful where you're pointing the hot air gun.

So far I've used them in 2 outdoor LED fixtures to add a longer cord to them.
The solder melts and flowed fine. All in all I'm very happy with the purchase and will definitely be buying more.

I have never seen or heard of these before until just last week I was on here shopping for regular heat shrink butt connectors. I clicked on this and now that I have them, I'll never buy any other type than these. You can see inside the covering, you line up your exposed wire leads in the center where there is a small bit of solder, you put some heat on the tubing to seal up the ends then work your way in and it melts the solder onto your connections, and you can see it work! I put a decent amount of heat on it from my torch and the tubing did not split like some cheaper plastics, this got pliable,easy to move around near the repairs, sealed tight, did not split or crack, and I covered up my repair in the wire loom and some electric tape and feel confident these will hold up!

This solder sleeve works exactly how it is described and kills two birds with one stone of soldering wire as well as sealing the connection. It is a huge timesaver and a necessity for those that don't know how to solder properly.

There have been some negative reviews that the plastic melts. This is completely untrue unless you are holding the heat source too long (and not using a claim which I'm sure some people have attempted to do) and trying to melt the metal ring as opposed to just heating the metal ring. I'm sure those that are saying that are trying to melt the metal ring which is not the purpose. You are only supposed to heat it up so that it melts the solder inside and flows into the wire.
I took video of the process and will try to upload to YouTube and put a link here. I have attached some photos for you can see the melted Sauter coming out the ends of the metal ring and it is nowhere near melting the plastic.

Perfect crimp-free connectors. They include low melt solder, two areas that form a waterproof seal, and the heat shrink itself which acts as another water barrier and forms the insulation.

I had no idea that these things existed, I'd always soldered and used heat shrink tubing. I was provided a sample in exchange for honest and objective review, and I'm so glad I found these. Awesome!

Where were these things years ago? Worked great with a heat gun. Could use a hair dryer. Fairly low melting temp makes them work so easily. Makes a great watertight connection.

Great product. Just used these for the first time and very pleased. Exactly as described. The transparent sleeve makes it easy to see if you have good overlap between the wires and, after heating, to see that the solder has flowed to encase both wires. After shrinking the ends over the wire insulation they appear to be watertight and to provide strain relief. No more soldering or crimping wires together only to realize I left off the shrink tubing. I have mentioned these to friends of mine and imagine a number of additional orders will roll in.

It took me only a short while to figure this out. I ruined a few by overheating and not heating evenly. Once I figured out the amount of heat needed, I was soldering and shrink tubing like a pro. I redid all of the connectors electronics on my boat with this. Well worth the money, well worth the effort.

Don't know why i never saw these before. This makes butting wires together so much quicker, Better and more efficient. All you need is a heat source and your good to go.

Only note i have is on the smaller wires was hard to not melt the insulation trying to get solder to melt.

Just be patient and you will be amazed.
