Well it's a USB drive that works, holds 3.71GB of files after formatting and testing on my computer shows it can write about 5-6MB a second. So for a drive that costs less than $10 definitely an excellent buy. The only drawback with this drive is the cap can't be stuck on the back of the drive while it's in use like some of the other drives I've owned, so you just have to keep track of it or you'll soon find yourself losing it which is an inconvenience. But as long as the cap issue isn't a dealbreaker for you, I see no reason why you shouldn't consider this drive, it's well priced, reliable and works.
I am very satisfied with this product. I never had the old problem of non-saving files or damaged files when putting this flashdrive in the computer. I'm using a Mac, and I am often transfering files from Windows and it works great. I recommend it!
