DFRobotShop Rover V2 - Arduino Compatible Tracked Robot (Basic Kit)

Kit came disassembled, which was okay by me since I love building things. No Xbee sockets, so I am having to purchase these separate and solder them. Kit seems to be well built, with the exception of the tank treads. After assembling, the left tank tread broke, leaving me with no choice but to order another. I might look into upgrading the tank treads, but this platform seems to be good. However it could be better.
