Nice price, and all of the 10 which I received seem to work. But as other reviewers have noted these drives are not very fast compared to other USB 2 "Thumb Drives" that I have tried (and I have tried many!). At less than $4 each, however, they will generally not be a problem.BUT, these drive have a UNUSUALLY BRIGHT RED LIGHT on the end opposite the plug, which blinks when they are working, so I would not recommend them for playing MP3 files in vehicles, unless the vehicle's USB port is in a closed compartment like the glove-box or the center console (or otherwise completely out of your peripheral vision). They flash as bright as a hazard alert and could be distracting even in broad daylight, and in my opinion WILL be an unsafe distraction at night.Recommended, but with that caution.These work great and at a great $ sale price for the 5pak the day I bought them.I use them for USB booters, and I like to use certain colors for certain programs, so I bought a few different color 5 paks.They work great for creating usb boot sticks using your windows programs that can make them, and USB2.0 is more than fine for that purpose.The did not say VICFuN on them when I bought them though (were solid color) I would not of bought them with their logo on it!My husband downloads things on these for me and some worked while others wouldn't. I will not order these type again.Perfect for my useMy husband was wanting something that would fit a family history on to give as a Christmas gift to his siblings. The 4 g was just the right size and the price was right. We looked in stores and everything we saw was way too big and to much money. This was just right.These USB drives all worked just fine. I reformatted each, then uploaded a mp4 video file to each one for delivery to players on a school sports team. No duds, and the HD videos could play right from the drive. I'll buy these again.They are not flimsy and have a nice blue anodized aluminum look. They seem to work well as USB drives too, but I haven't transferred a ton of data yet.Arrived on time and in great condition. I saw a review that said they weren't that good, but my experience has been they all work well. I tried them out and the performance did not let me down. Great price and thus far a great value.
