Very disappointing 121

I confirm all the arguments of the previous comment, and I add the following:
- Transfer rate recorded in writing tip is 800 kb / sec on PC port USB2 otherwise reaching 10 MB / sec with an external hard drive. It's very very slow (barely above the 4x CD burning). And average speed collapses with small files.
- Autonomy with a recharged battery AAA 600 mAh Ni-MH is ridiculous. From the order of 2H.
- The color change of the display with each manual action can be disabled. It's very unpleasant.
It ruins everything. Too bad, for an accessory with such functions. I am very disappointed.
