I got it with hardware version 1.6 (there are also 1.0 and 1.4). Has pros: The price (at the moment) is lower than in China. I picked up the E1550 (Megafon) and MCD-650 (Skylink) modems without any problems. Familiar TP-LINK web-based configuration interface. Nice option to automatically switch between WAN and 3G. The kit has everything you need. Got cons: Body color white. There is no output for an external antenna. Short usb cable. I fully admit the manifestation of some more problems during long-term operation, but from the experience of using other TP-LINK equipment, I can say that they are eliminated quite quickly in new firmware.
