    I own a few of these, they work great. I use them mostly to add storage capacity to my Nvidia Shield's, but I also use them for other things, I like them because they are low profile, also when they are new, they can be pretty tight fitting, and hard to remove the USB ports in part because of their low profile size.

    I have been using these for 6 months and they are solid, well built and are almost flush with the USB port. The larger stick USB drives are more likely to get bumped into and broken so I prefer these. Samsung work better for me than the off-brand thump drives that regularly fail. Highly recommended.
