Speed： As I write this review, I am waiting for movies to transfer from my laptop to 2 of these USBs. They're write speeds are 800 KB/s and 1.2 MB/s, about 1/10 of the advertised speeds. One of them took 1 minute to format, and the other one I had to try 3 times before it finally did. I have a 3rd USB plugged in and formatting and it has been stuck in a loading loop for 10minutes. Quality： If these 2 USBs I am writing to end up the same as the 3 I used 1 month ago, they will be corrupt some time in the next 7 days, or the USB-C port will become unusuable because the storage "slides" within the metal housing, like a turtle into its shell, making it useless. Value： Cheap, but useless. I am only writing this review because of the spare time I have to it, while waiting for these absolutely awful devices to do simple tasks.
