Not bad, but why 4200 maAh? Using 3x Scud, You should be getting 4500 mAh, and, considering effect of current from every cell /3, it should give You ~4600 mAh of usable capacity under heavy load (even more under low load).

Also, does the camera lens cover work at all, or is it fixed in "open" position? And, what the hell is that "grey mass"?
