Aebitsry 250PCS Solder Seal Wire Connectors, Mixed Solder Sleeve Heat Shrink Butt Connector, Waterproof Electrical Terminal Insulated Splices Kit for Automatic Marine Boat Electric Work

I've used similar sleeves previously and needed more so I bought this pack. On reflection I should have bought more with the smaller sleeves as most are too big for my purposes. I've used some of the smallest ones so far and whilst they are ok, I've had issues with them splitting under heat which I never had with previous ones. I'm having to be far more careful with these ones.

I've never really been sure what constitutes 5 stars in these ratings TBH; though I contribute...It has, in my opinion, a disproportionate range of what is most likely to be used; hence not 5 stars.A very good product which I would recommend.

I didn't even know something like these existed, but I'm glad they do. Not being the world best person with a soldering iron, these help make electrical joints like a pro. Very easy to use, must keep rotating when applying heat.

These are great for attaching copper wires especially if you need to waterproof. Easy to use. The best way is to use a heat gun when joining them.Make sure the hear gun is on high heat, join the wires first and ensure that the heat melts the solder in the middle, this will form a bond between the wires. Strong connection.

Good product, worked well

TESTED ONE TODAY AND WORKED AS EXPECTED

Great

Makes my wire connections look great
