I've never had a problem with any of my Transcend cards, both SD and CF, and now I have a Transcend card reader and flash drive. Never let me down and never let me down Probably the most reliable cards I've used and the price can't go wrong. I use SD cards in my Zoom H6, Canon T2is, T4i, T5i, XA10, HF R300 and sometimes just for data storage. Everything is reliable and depending on the speed of the cards you get, they're on par with Sandisks but at half the price. CompactFlash is the same comparison for me. Lately I've even given up on Sandisk because Transcend continues to live up to expectations. The card reader is just as fast if not faster than my Lexar Pro Edition card reader (can't remember the model). My Transcend USB 3.0 stick that I use for everything.
