I've used (and sadly lost) many USB flash drives over the years, so I though that getting a 16 GB model would be a tad too risky. I knew Kingston to be a good technology brand (despite never having used them) so I though that i would try a large capacity USB stick.
There isn't much to differentiate USB pen drive (besides capacity) so the main criteria are durability, reliability and design perks.
This peripheral device is very durable, the case is very hard and the swivel design means that the actual technology is protected most of the time. But one great thing about durability which isn't mentioned it that fact that it is waterproof. As I was swinging my keys round my finger, the whole rings flew off my finger and landed in my sink. Horrified that my £40 USB was ruined, I dried and tested it to find that it worked perfectly.
I've never had any problems with the flash drive- so it is very reliable (100% so far!). The design is OK, nothing special at all, so don't buy this if you feel a USB pen drive is a fashion accessory.
Overall, this is a good, large capacity USB drive well worth the price- very durable and very reliable.
