Review: Really good - I've been super impressed with this heat shrink. It shrinks up really well, has plenty of adhesive inside to seal and rarely melts through, even when I use a torch to shrink it. It's a decent selection and feels heavy duty. A lot of heat shrink you can feel is just super thin, this stuff is much better. When I run out I'll buy this brand again.
Review: Good product, good percentage shrinkage in diameter as well with little in length - Good variety of sizes in well organized and convenient plastic case. Works well, is a little thicker thickness than other clear heat shrink which may be a plus or a minus depending on your application and preference. Description says it may yellow slightly over time. Have not observed any dis-coloration as have only recently used produce but I amusing it in part as a protective sleeve to help keep Casio Labels around cables/wires for identification so this could be an issue after time. Right now the heat shrink appears crystal clear and the underlying labels are easily read and look very professional and will not peel off like “unprotected” self adhesive labels.

### ⭐⭐⭐⭐⭐ Shrinks a lot - and that's good!
*by D***N on March 3, 2021*

Pleasantly surprised. Went to cover some 4ga battery lugs and the tubes looked way too big. Tested one by putting it on a screwdriver. I didn't expect it to shrink that much, but wanted to see how far it went. It shrunk all the way down and glued to the screwdriver. Very pleased. Good thickness - nice and heavy over the lugs. Another nice feature - they are so big you don't have to remember to put the shrink on before you crimp the connector - plenty big enough to slide on after you crimp. Haven't checked, but I would also like some that are a bit smaller, for smaller gauge wires (18-20ga tefzel, unshielded, for example.)
