I trust SanDisk to deliver high end products which is why I don't mind spending a bit more for SanDisk products. I had issues with other brands writing to disk (when used with a phone) and I had one card fry on me. One could put blame on device for frying a card but card should be able to tolerate high temps, as does SanDisk. Highly recommended product, specifically for Samsung Galaxy S3 phones. Cheers.
