Summary: Good electrical performance spoiled by poor packaging.
Pros: Electrical performance is up to spec, fast and easy to format and use. USB 3.0 speed makes this flash drive fine for moving large files. The performance can't be beat for the price.
Cons: The slide retraction mechanism has poor detents, the drive tries to retract when you plug it in. The hole for a key ring is far too small---don't these folks carry their flash drives with their keys?
Summary: Just tested it on my computer with usb3.0 port R / W 98MB/S 34MB/S The writing speed is very bad to an USB 3.0 flash drive , while it's not bad for the price I paid ( only $1.08 after coupon) For the people who wants a real usb 3.0 flash drive , please refer to sandisk cz80/cz88
Pros: Bought 2, used 1. Likes it so much bought 3 more. If all five are as good as the one I've tried, I'll be very happy Fast and well built. Also bought a PNY 128 gb, failed out of the package, left comment there!
Summary: Great capacity per dollar! Rubberized grip really gives it a nice, premium feel. I like that its a slider - no cap to lose! However, it is too easy for it to slide out while pushing it into a USB port so watch out for that.
Pros: High capacity! Fast!
Cons: Slider moves easily when inserting into USB port. Not formatted NTFS/exFAT out of the box for large files. Thick body - it will block adjacent USB ports!
