Average performances but practical

Bought for mp3 playback on USB drive (also used on PC)
The +
- Super convenient size for a car or a laptop
- Very light
- Despite its size, is easy to use
- USB v3
- Price as tight as its size

Les -
- Heater is weird, this is the first time I see a key heat in this way, but for now no failure
- Very average flow even USB3 (Little more than 20 Mbit / s write and 80 Mbit / s read, far from the 100 advertised), but unimportant to music (depending on what is done)
- The size is small but on a laptop than 1cm still difficult to leave it in place during storage, damage

In short a good buy, seems average, it will not be expect miracles (at that price anyway ...). Its main advantage is its size, so only buy if you are interested in this aspect (car, discreet transportation, no place, etc ...)
