Review on XHF 205 PCS 3.5" 3:1 Adhesive-Lined Heat Shrink Tubing Kit For Auto And Marine Applications by Vera Gashi

I used this to stabilize the old brittle cloth and rubber insulation in the electrical boxes in my home. The piece of mind is incalculable. It's super easy to use, feels at least as thick/durable as factory wire insulation and it shrinks MORE than 3:1 in diameter without loosing ANY length at the low setting of my heat gun.To address 3 complaints I saw in negative reviews;It does shrink MORE than 3:1. Remeber it contains an interior adhesive layer AND when you shrink the plastic, it doesnt magically dissapear, it collapses on itself, getting thicker. so while the OD (outside diameter) may not appear to do so in one posted image, the ID (inside diameter) which is what matters, shrinks more than 3:1. The 1/4" will shrink tight over a single bare 12 guage wire.The other complaint I noticed was about the case. The case I got is very good quality, of flexible durable and clear plastic with hinged plastic locks (not just fold tabs, I hate fold tab locks) and a hang tab for store display that works great on peg boards. I'm a freak about tool room storage. I dont have a single jar of screws. everything is separated labeled, i probably spend as much on storage solutions as I do on tools. I'm not even the least bit tempted to replace it. The only issue is that it comes with 8 sizes of sleeve in a container that has 4 compartments, but that's really nitpicking.The last reason I saw for negative reviews was they are too long. This is never a bad thing. It's easy to trim with a scissor to any size you need. Too short and you're out of luck.Too long? Not a problem. Cut what you need and save the rest of the next time.
