Just bought a Qcool yesterday and am testing it.
1. Much smaller than G2 - perhaps have the volume. The cosmetic
finish is nice and smarter also, aluminum (partial) case.
2. Much slower than G2, I timed 3' 45" for a 128MB card - thus
takes twice as long than the G2
3. Accept different types of cards without adapters.
4. LCD display is OK. It is a small but legible dot matrix LCD.
When switched on, it shows the no. of files properly transferred
last time, then the remaining capacity of the hard disk.
5. Does not allow single file transfer, nor transfer from HD to CF
etc. - this is acceptable to me.
6. Transfer speed from HD to PC is also reasonable.
7. It supposed to turn itself off 15 seconds after file transfer.
Mine turned off the HD after 15 seconds, but the display is on
forever - locked up. I think I have a faulty set.
