I am fully satisfied with this key that I use to store my music and listen on the car radio.
She does not have status LED, what I was looking to avoid a continuous flashing on the dashboard in use (annoying when driving at night: this is not the case of its main competitor the Sandisk Cruzer Fit has a status LED that flashes when used).
Key high quality (Kingston) and very small (no risk of hang or break when in place on the dashboard).
When removed from the car dashboard or computer, it clispe well on the cover (no risk of loss of the latter).
It has a hole to slide a link so I can hang it on the key ring without the risk of losing it.
When copying music from the computer (Windows Vista), the write speeds were between 4 and 9 MB / s.
I have to date copied about 90 albums (about 1,570 songs) to WMA, MP3 and AAC, and all are read easily. I thus uses only 5 GB on 28.8 GB actually available. This leaves a margin for future albums.
In the end, ideal for portable use key to store music to a car radio or to be used permanently on a laptop without risk of breakage: So I highly recommend !!!!
