Great for marking cables and gear, which is what I use it for (that is why I bought an orange tape), and will do well for other tasks as well. Only thing that annoys me a bit is the fact that you have to use scissors to cut it if you want straight lines. It's not like your standard duct tape that you can just rip off and have a nice, straight line.
I initially bought this tape to make I.D marks for a cable loom. The tape is incredibly high strength and very sticky. I've found uses for it everywhere. From electrical repairs to I.D tagging gear and flight-cases
