Hi
I have been having problem right from beginning i got Zumi. Not a pleasant experience at all. Initially the zumi doesnt go in straight line and could not resolve calibration issue despite doing as u suggested. Now it doesnt start at all. Always shows up waking u p on thr screen and doesnt wake up. I guess i have a problem in the product i received. Can i get a replacement product. Thanks.!

Hi.. I did as u suggested. But still no improvement. The zumi doesnt get recalibrated and still doesnt go in a straight line. Is there any problem with device itself ?

Thanks. yes i swapped the motor connections. Better now. But the directions are not entirely correct. How do I recalibrate. The Recalibration code in example shows permission error.

Hi My Zumi got a problem. It moves backwards when I code forward and vice versa. What could be the problem. How can I get through this ?
