Review on SanDisk MicroSDHC Memory SDSDQ 004G Packaging by Brian Delgado

Very disappointed with this product. Bought 2 maps for use in phone and tablet and neither of them work decently. The reason is that the cards are not original Sandisk, just fake copies. I've tested this a number of ways (SD card reader found the wrong vendor ID; the card itself doesn't have the correct labeling on the front of the card, wrong packaging). You might get lucky depending on what device you're using. I've had no luck with a smartphone, tablet, and Raspberry Pi. The card works for a while, then it just hangs and becomes unreadable. I'm not even sure if it's actually 32GB; Files take forever to load (and I have real Sandisk cards which are 10x faster) and if you look at the card yourself you can see the difference between a real Sandisk card and this one. While it's cheap, if you're using it in your camera, or worse, as the main drive for your embedded device, or as storage for your phone or tablet, you don't want to risk losing your precious data. Buy from another supplier, mine was supplied by "Skysun"; I'm not sure if it's just this provider or if they're all the same. I am contacting Sandisk USA to get the final say on whether or not they are actually made by Sandisk.
