How Good Is Cheap Kapton Tape From eBay?

Kapton is a polyimide film developed by DuPont and can tolerate a wide temperature range.   "Kapton" tape is used in electronics for applications where high temperature resistance is desired.

On eBay I bought some "Kopton" branded tape with a temperature tolerance stated as being long-term 260 °C short-term 300 °C.
