Bests & Worsts Reviews from Amazon

Bought the 128gb less than a month ago and am heartbroken to report that the flash drive is not showing up on my mac laptop, my husband's laptop, my tv or my iphone 6. I just spent half an hour googling ways to fix this thing and another 30 min chatting w/ amazon tech support. OHHHH. Whhyy????? I chose "SanDisk" because out of the dozens of similar generic looking products, I recognized this brand. But to my shame and stupidity. I'm so upset. I just moved a bunch of my kids home videos to save room on my laptop and iphone. I am feeling really low. I would prefer to recover the data before I mail it back to amazon so I'll need to spend another hour reading yelp reviews for tech support here in L.A. who might be able to handle such a thing--though I fear that's a waste of time because this thing is probably dead dead dead. But I'll probably do it anyway and pay $100 or more. It was great for the three weeks it lasted. But I would never buy this again or from this brand again. I feel like a limb's been cut off or something.... If you don't want your heart sink, don't buy this thing!
