Summary: I have this flash drive on my keychain and with 8gb, it is a nice size to have on the go. I've had this for about two years now and of course these things get banged and tossed around but it still works. I'm sure my keys have been temporary wet or hot or whatever else and there has been no damage to the data on the device. It's small enough that it's not a huge presence on the keychain.
Summary: It's a USB flash drive. It's not that big a deal. It does what it was designed to do and kt was delivered on time for a good price. I have used this many times over the years and it never fails me.
