Documentation needed
Hardware is fine but setup was tricky. Had to find external drivers for the USB bridge. Would be better if a guide was included.

Good board, minor issues
Great value for the price. The pins are a bit tight for some breadboards, but functionality is solid. Bluetooth pairing was quick.
