After reading all the good reviews I thought damn yes this would be way better than using dirty thermal paste/lube, WRONG! Thermal conductivity is complete nonsense! Now it's the sticky competition to 3M VHB tape. I was working on a Peltier project that worked great with thermal paste. I wanted to make some changes to the setup so I used this tape to assemble it and it didn't work like it used to or didn't work at all. I thought I might have damaged the peltier element so I reworked it and did the same thing. So I redid it for the third time using thermal paste and original technology and Bam works great. If you want some damn good double-sided tape, this thing will stick to a wool blanket. Otherwise I would recommend thermal paste. Lesson learned for $13.
