Review on Gigastone 8GB 10-Pack MLC Micro SD Card: High Endurance Full HD Video Recording for Security Cam, Dash Cam, Surveillance - 85 MB/s, U1 C10 by Badpuppy Warton

I used this card as extended storage for my mobile phone. Everything went great for the first 2 weeks. One day I wake up and find that my phone is throwing error messages saying the card is corrupt and needs to be reinstalled. After plugging it in again, same error. I tried to format it and got the same card not working error. It's good that in just 2 weeks I lost data, photos, videos, applications, documents forever due to poor quality on this card. Do not buy this card if you plan to use it for confidential, important data or anything else that is important to you.
