    Overall, a great option for cheap transfers of large amounts of data. It is all plastic so its not a good daily use option as well as its too slow to use for TeslaCam storage.

    Solid read/write speeds from this flash drive mates with a compact form so you can keep it plugged in all the time. Only drawback is given the tiny size it is very easy to misplace.

    Smallest thumb drive I can find. Matter of fact, this is so small that I have to attach a lanyard to it so I won't lose it. Got this on sales, and together with my point, I on;y paid $5!

    No too crazy about it being so tiny and not coming with a string to attach it to anything, but it does what it’s supposed to do and smoothly so I’m satisfied. Good buy.
