I have a Bushido TDF, probably from the same vendor. No issues. The firmware update lets my SRM control the power. Works great. I did have a situation where the flywheel half of the brake became dislodged from the frame, which lit up all red lights and no power output. I had to snap it back together. These things aren't like dumb trainers, they don't travel well. Once I fixed it, I haven't had a problem since.
