it is really worth the price. the product came with all of the necessary parts and tools without any lost items. they even sent me additional screws and nuts plus battery box (without batteries) I assembled it easily and it worked with the DOIT kit just fine and clean. be careful about the chain wheel. for shorten the chain you just need a piece of small peg and a hummer by choosing the right direction by just some hit the pins easily come out of. after buying you will be excited by completion of the product I recommend this product for being familiar with robotics and working with microcontroller
