[This review was collected as part of a promotion.] I’m really happy with this 512GB UHS-I card. It has plenty of storage, works great, and the transfer speeds have been good for what I need. I like having the extra space so I don’t have to constantly delete or move my files. So far it’s been reliable and a good value for the price.
