I bought a 32GB and a 64GB drive each for OS installation and general use. I tested both with H2testw, both drives were genuine and within their rated capacity. I also ran a speed test with CrystalDiskMark and got about 235MB/s sequential read and 40MB/s sequential write, which is frankly excellent considering how cheap they cost. They get hot when transferring a lot of data, but not dangerous. High-performance flash drives like this generate a lot of heat anyway, and the metal casing seems to dissipate that heat well. The physical design is also excellent. It's solid metal and quite small, maybe half the size of a regular flash drive, but I think it's a good size. I like that it is capless. The keychain hole at the end makes it easy to pull out from the USB port. I attached keychains to each of them as a string so they can be easily distinguished from one another. Overall I am very happy with them and would recommend them. The performance is great, the design is great, and they're not expensive at all.
