Yeah I was interested in the R3 but after my experience with 3 R2's I am hesitant on the quality. I could even get mine online but anytime I tried to access dumaOS it would time out the connection, then just at random as well.
I would get to a white setup page, then when it would try to go to dumaOS it would say it failed to complete setup. I could only get to this page offline as well. Could never get to it while online.
