Best High Heat Wiring Sleeve
This stuff is perfect for what I needed. I was running reverse switch wire through my engine compartment, into the cab of my car for a manual swap. The engine puts off some serious heat where I need to route the wires. This sleeve is the real deal. Will come back to this stuff for wire bundles small and large!

Very Good Quality
I bought it for my waffle maker that wasn’t heating up. I opened it and found that the problem was the cable covering was burned, which caused the issue. Fortunately, I was able to find this heat resistant cable protector of very good quality. Good product.

A Unique Product
I bought two rolls of this product to protect the rewiring I’m doing on my teardrop trailer with silicone wire. I’m amazed at how flexible it is even though it is made from a combination of silicone and fiberglass. Thank you Buyuneed and Amazon!

Puttin on the Ritz.
Restoration of an antique aircraft and I needed a sleeve to protect wire bundles. This worked perfectly and matched factory sleeve. I'm happier than a Ritz cracker with cheese whiz and bacon.

Works great for me
I'm using this to protect some wires that are running close to a heat source on my vehicle for a little extra protection. The sleeve is fairly easy to push the wires through although it may become rather difficult depending on the length of sleeve or size of the wire vs size of the sleeve. I haven't pulled the wires out to see if they've been damaged as that would take a lot of work but everything still functions so I'm assuming it's ok.
