PREMIUM Solder Seal Heat Shrink Butt Connectors RED 100 pcs Electrical Connectors Waterproof Marine Automotive Wire Connector Kit RED 18-22 AWG Gauge

Great little items to have if you suck a soldering. Not even Gilligan could screw these up. Well, never mind, he did spend years on an island with Mary Ann and Ginger, yet still stayed in the skippers hut. Heck, even Mrs. Howell would have been a better choice. Oh ya, the product. Easy to use, I've gone though about a thousand total.

Works well - red slot on crimp tool works perfectly. Heat shrink seems to be tight and thus should protect the connection from moisture. I have used these for Christmas light strings (LED) and we shall see how they hold up after being out in the weather. At this point, I highly recommend these for quality and price.

In the past I've used crimp connectors, done soldering + heat shrink tubing (or electrical tape), and other crazy solutions too hacky to mention here, and these take the cake in terms of usability, durability, and waterproof-ness.They are just so easy to use. You strip the insulation off of 2 wires, shove them in, and hold it over a heat gun for about 30 seconds (wait for the solder ball in the middle to melt and get round on the edges) and presto you have a water tight connection that is also very mechanically stable because of the soldered conductors inside.I made a custom RGB LED Christmas light setup with these (probably used about 200 connectors), and they held up outside in the very wet Seattle rain with absolutely no problems. Highly recommended. These things are amazing.

as an avid holiday light show hobbyist, i use a lot of different length light strands. this product makes it easy to solder wires together and water proof them at the same time. i will be using these for all of my soldering needs from here on out. gf

Works as advertised. Good price/value.

Ok, so at first I thought I was going to be really disappointed. I’ve never used anything like this before so I guess I didn’t know what to expect, but wow are these things great! I was heating up the connector and heard sizzling, and I thought I was just melting the plastic. Turns out I wasn’t, yes the plastic gets very pliable while hot, but once it sets you have a very strong hold! I was surely surprised. If you’re thinking about using these in a place that’s not really ideal to use a solder iron like me or you simply don’t want to use one then I highly recommend you give these a try. I’m going to be using these to connect wires for a headunit installation in my truck.

Complete junk! These things are completely worthless. The solder does not melt and fuse the connections together as advertised. Total waste of money!

My father asked me to order this for him. And now he is very satisfied with this purchase . He use them for wire connection. What is a big advantage is waterproof and resistance to overheating. By the way you can watch really helpful video, so even I understand how to use it
