I like the AA battery style design of Duracell’s new 32 GB Rugged USB Flash Drive. They feature a solid, Black rubberized housing with the famous copper ring. You won’t have to worry about losing the cap because this drive has a twist mechanism like a twist flashlight that will extend or retract the USB connector from the body. It even has a corresponding ratchet sound when it’s twisted opened and closed. A 5-year warranty is also offered for each drive. It’s available in 16 GB and 32 GB capacities with prices from $12.54 – $24.60 on Amazon.
