I'm running one of these on my Lowrider 2 and it's pretty great. The only real issue I've had was with limit switches (I got cocky and didn't use shielded cables, then ran the sensor cables with the stepper ones, so I had to add pull-ups and filtering caps to smooth out the noise... lesson learned!) The web interface does seem to crash semi-regularly if you step off the straight and narrow but once you know the pitfalls it's great to be able to drive your router around with a laptop or phone, and to be able to upload files over wifi.
