I've had a very good experience with these, I hope you will too. Be sure to buy a high quality (endurance) microSD card with reasonable capacity so they aren't corrupt after a short while. I have a Samsung PRO Endurance 32GB in use for 2 years without issue, recording 1080p for about 3-6 hours a week. I also have a SanDisk High Endurance 32GB for about 5 years with the same usage.
