This is around the 6th USB memory stick I've owned and it is great in its own ways.
Build quality is faultless.. it seems really good to me for a drive this price. The metal and plastic is blended in nicely.. and the size is the smallest I've ever had. 10/10
When it comes to performance.. it's a strange one. The write speed is about 4MB/s (my last cheapo drive did 8MB/s!!) which for most is fine... but if you're constantly filling it with 15GB of data.. that'll take you an hour each time. 5/10
The read speed averages at about 28MB/s which is great.. but for the first 160MB it crawls along at about 16MB/s.. before shooting up. 8/10
Overall I'd give it 8/10.. it's great value but really slow if you're constantly writing tons of data to it. If you're just going to put bits on at a time.. its fine.
