I have this card in my second 70mai dashcam that gets HOT. I couldn't believe it when I took it out of the cam after a drive to view some files on my pc. It was almost burning my fingers. Mounted on the windscreen near the roof in a closed car outside all summer long, it gets HOT. The card has to record two video cameras simultaneously and continuously, one 1080p and the other 2k. It has been going for two months+. I am really surprised that it is performing perfectly. No news is good news. Will update if it fails. I have a competitor's card as well doing the same function in another car so it should be an interesting durability contest. Winter's coming!
