The flash drive looks just as good in real life as it does in the picture, and feels very good and reliable. My computer recognized it immediately without formatting. I ran the Flash Bench utility to measure read/write speeds and it worked fine, but not as fast as the Sandisk Extreme. The reading speed was around 115 MB/s and the writing speed was around 25 MB/s. The Sandisk Extreme had read speeds of around 250MB/s, but write speeds were around 100MB/s, dropping to 50MB/s for smaller file sizes. So if speed is your main consideration, get a SanDisk, but Sanfeya drives are a lot cheaper and perform better than many other flash drives I've tried. Beware of some drives that claim to be USB3 but actually run at USB2 speeds! If you're only copying a few small files at a time, any flash drive will do, but if you need to copy more than 1GB at a time, a faster drive is worth it. It's a pretty good compromise between speed and price.
