Everything comes from China products reviews site purchased in China
An Arduino Uno is a little expensive, but this copy of GeekCreit brand It's cheap and good quality. Ordered two!
Comes with a riser for projects and a label. Does not come with cable, then it gets even cheaper.
Nothing to complain, all pins are there, all regulators and components. Is going to work perfectly.
The ATM328 processor is the SMD version, which doesn't make any difference. Standard Arduino program drivers recognize the card normally.
The form could be better, but no complaints considering the price.
Now that the recipe is respecting more orders, and not taxing everything you see, buy Arduínos in China went back to being a good deal. I leave below link to the product:

To achieve allocate the COM port has to follow the link that is in the product specifications in Banggood :https://www.banggood.com/UNO-R3-ATmega328P-Development-Board-For-Arduino-No-Cable-p-964163.html?rmmds=myorder&cur_warehouse=CN
Only after the installation of this driver is that it has access to the board by COM port.
I hope that solves your problem.

I bought 4 units and the arduino IDE 1.6.9 does not recognize the door with any.
Detail: the one I have has only a 16 MHz crystal, While the other I have and work have a 16 MHz crystal to the arduino and other 12 MHz crystal to the on-chip communication.
Can only be the FTDI driver, that makes the USB communication with the IDE. Try following these tips: http://www.instructables.com/id/How-to-fix-bad-Chinese-Arduino-clones/
