Hello fellow user, There is currently no way to find out if you are purchasing the revised or old 2021 model. However, I would suggest that you purchase the RM850x 2018, as I would advise you not to risk it, as it is more likely that you would be getting the old 2021 model. Nevertheless, that is my opinion and your decision. The 2021 does not have any advantages over the 2018 model and the 2021 does not have the color white. Sincerely, Centurion
