Thanks for your reply. This unit out of the box is like that already. Maybe the recon guy didn't do a good job. Worse case I will take it apart and use as spare parts. I ordered 2 from woot.com and the other one is ok.
BTW I entered the serial no. and the warranty is one year.

That is the risk you have to take for getting a recon one, if you reside in US still not so bad as there's a 90 days warranty. If they know it's out of US, warranty voild immediately.
Try cleaning the sensor and check whether the wheels are clean. Since there's no warranty liao might as well dismantle it and do a deep cleaning.
