Review: Great for tool handles - If you're looking for wheel barrel handle covers, this is the stuff. Nice and thick, shrinks down tight and mine has lasted 2 years so far, and keep it outside. I'm ordering more for my 3rd wheel barrel. Also worked well on a hammer.
Review: Quality and quick shipping. Price was very good. - First impression in wrapper they looked like thin not quality heat shrink. But after opening up and cutting to length and heating on my new battery cables I made, this stuff is super thick and good quality sealer. Shrunk at least 3 to 1. I bought 2 more sizes and have used the larger ones. Very happy with this heat shrink.

### ⭐⭐⭐⭐⭐ Quality and quick shipping. Price was very good.

### ⭐⭐⭐⭐⭐ Works as advertised. My new shop standard!
*by M***B on July 27, 2018*

Works as advertised. It can be slid over the ends of terminals that are already attached, and will shrink a lot more than typical heat shrink to conform to the terminal and wire. I have NOT had any issues with glue melting at ambient temperatures, even 100+ degrees temps we've had in my area lately. In fact, I don't think the glue starts to melt until after the tubing starts to shrink. I've used it on 8 gauge and 10 gauge wire and connectors, so I don't know if this 1/2 inch size would shrink down to fit smaller wire OD. If the vendor sells a 3/8 inch or 5/16 version, that's probably what you'd want for the smaller terminals. Edit: I did some more experimenting with smaller gauge connectors. I couldn't get the shrink tube inside diameter down to less than .200". So I'd say a shrink ratio of 2.5 to 1 is more accurate, at least for the 1/2 inch tube. But I still think it's a nice product and will buy a smaller size if available.
