Today I ordered this model and was pleasantly surprised) The size of the adapter is much smaller than expected, only 68 x 2 mm. I took this device as a whistle on the second computer. stand, there the dimensions are an order of magnitude larger and against its background the 821N is just mini. Although, before buying the first adapter, I read reviews and judging by them and these characteristics of these two devices, they have a difference only in the presence of a usb stand, and so the same adapter and is no different from the 821NC. It is possible that this model is in the V4 ate with smaller dimensions
