Good product; wraps the wires right; worked as expected

I used it to repair some 12volt cable that had chafe areas and the shrink tubing worked great.

Doesn’t shrink down very much, and requires a tremendous amount of heat. Overall pretty miserable to work with.

Do not but those, too thick I think they're lacking elasticity they burn and doesn't melt.
