Summary: I have been very pleased with this product so far. I was a little wary at first just because some people were saying theirs were going bad very fast, but, besides it being a bit slow compared to the last thumb drive I had, it is a very good value.
Summary: For the love of God, do not just unplug this or any ADATA drive from your PC. Eject it first through My Computer. If you don't you can brick it. I have successfully junked 2 of these. It is a known isssue on Adata's website. I was able to recover and still use one, but the second is a paperweight.
Summary: This was my 'wallet' USB drive, used about once a month when I was out and about and needed to grab a copy of something digital. As of yesterday, Windows sees it when inserted, but only sees the controller, not the memory or its contents. It might be time to convert to Sandisk.
Summary: Believed the product was broken for months, with the seller being little help. Seemed like it was dead weight until I messed around with it for a bit and managed to get it working by "safely removing hardware". Haven't had this problem with any of the many other drives I've used.
