Can't comment on durability yet but it will be in my DVR and if there are any issues I'll update here. I ran basic tests to verify the 64GB capacity and full read/write tests followed by a speed test. So far so good, it lives up to its specs with read speeds up to 95MB/s and pretty good write speeds (up to 45MB/s). This is my second Gigastone product and I would say it is excellent value for money. If they also keep their guarantee promise, I'm pretty sure they could become a major player in this niche market. *** UPDATE 28 months later: This card is still in my DVR and keeps recording, never had a problem, I'm starting to think it will outlive my DVR.
