Regrets: (1) the notch of the screw at the rear, in the closed position is not aligned with the removable piece in which drums are, SIM card and micro SD card (while it is the case on the B2100); (2) the material covering the back of the mobile phone, if it is still adhering, is not as much as on the B2100.
Moreover, I preferred this model due to the presence of a LED flashlight as well as the tightness of the hull. So even if the lamp is admittedly a tad less powerful than the B2100, power remains respectable and it fills my needs. Moreover, the key person responsible for the lamp was moved to the right edge compared to B2100 (where the 2 keys 'volumes' and the lamp button are all three on the left edge, which is less ergonomic) .
Last but not least the battery, high performance, allows charging a week or even every two weeks in case of passive use.
I recommend it to anyone looking for a cell phone shock resistant and waterproof, and especially durable.
05/04/2012 EDIT: I forgot to mention a rather annoying problem which is a total blockage of the phone when writing SMS, and you just have to remove the battery; this only occurs from time to time, and when it comes to long SMS, but the fact remains that it is a defect of the phone in general and not specifically of mine (confer comments on Amazon.de or Amazon .com). And I can assure you that when you lose a SMS in full writing is annoying ... Finally, this phenomenon is not too common, fortunately.
