fast shipping. film tape was more than i though. very thin. strong. great adhesion but no residue. i am us8ng as anti conductivity barrier on switch c9nnection tabs where solder and wire is bare. to resist possible short circuits or touching by hands... basically wrapping parts to keep safe and i did heat lightly and it seemed to set it up and kick like ub 2poxy woupd. quick and now it 8snt sticky or able to remove easy. basically it is awesome and necessary for any electronics lab and if you are DIY or experienced then just buy it because you need it even if you never heard of it.

As expected, great value for $

Color: A-Yellow-2 Roll

This is exactly as described and what I needed to prevent heat creep from my hot end to the thermistor on my 3D printer. I no longer am replacing thermistors regularly with proper protection in place. There is a lot of tape that comes with the order. I could have paid attention and ordered something a little wider, but this works well enough for my needs.

Makes patching wiring a breeze

I use this for repair job on an antique light fixture in my Victorian home. Work like a charm. I’ve got plenty left over and I have a feeling I’ll be using it in the near future.

Super sticky!

I find all sorts of uses for this tape. It’s super sticky on both sides and could be used for a wide variety of applications. Maybe an eighth of an inch thick, which works well for uneven surfaces. My last use was hanging mirrors on the wall, and it worked great.
