Durable but ... 1) Shrinks slowly 2) Maybe not quite 3:1
It's Ok. It takes a long time to shrink to its minimum size. It's thick material and the glue has to heat-up. I'm not sure that it shrinks down from 3:1. It seems to come-up a little bit short on that. Your results may vary.

True to size, high quality, durable heat shrink tubing
I really like Wirefy Heat Shrink Tubing. It works well and has been very durable for every application. I've had zero issues with moisture or tear. It is true to size. It leaves very little residue if needing to be removed, but the adhesion is strong enough that there is no slippage once the shrinking is accomplished. Great value too. Flexibility differs depending on the type of wire used, but I find the 3:1 to be sufficiently flexible. I also find that the listed heat shrinkage sizes are true. No issues. Lovely product.
