Seems to be a hit & miss based on that thread and I am not sure that people actually got the real 3M VHB kind. If it was not a camera I would not care whether it's 3M or not. I just might order a a pack of 5 mounts and throw in some stickies.
It's not a bad idea, based on the fairly low cost.
I'm still waiting for them to return my email, regarding the focus issue with my second camera. A good product can be let down by bad service.
