As far as I can tell this is a 'genuine' R3 Arduino board in an 'official' box and mounted correctly on a clear plastic plate.
I need good A/D performance for my application, so having a board that fully meets the ARDUINO MEGA 2560 R3 specifications is important to me. Almost all the R3 clones you can get at a significantly cheaper price do not have the components fitted that are supposed to decouple noise from the ADC Vcc line (pin 100). Clones usually have AVCC connected directly to VCC in order to save cost as those components are not 'essential' for correct operation. If they are missing and you want good A/D quantising noise rejection it requires some VERY careful micro-soldering to add them. This board has those components fitted.
