Worth it!
Many sizes to choose from and they shrink perfectly. They fit multiple sizes easily and quickly.Holds together good and keeps the ends protected. Easy to shrink with hairdryer or a heat hun..Works for multiple applications.

Easy to use. Quality solder joint with moisture barrier
Made replacing my Malibu's low beam headlight socket much easier. Good quality. Easy to get a quality solder joint without wrestling with the wires, soldering iron and solder. Just fit the two wires to join under the solder ring in the tube, heat it.

Excellent Quality
This is the second time I have ordered these. I have used them for multiple boat trailer wiring jobs. I highly recommend to anyone who does wiring. I use them with a heat gun for the best results!

The good and the bad of it
The smaller ones the solder melts great on the bigger ones you got it put 40,000° on it and then the plastic melts way before the solder melts is a matter of fact I couldn’t even get the solder to melt on the big ones

Doesn't work. Tried several. Have seen the solder flowing, but after cooling down, I could easily pull them apart. Went back to good old soldering iron and shrink sleeve.
