[milimbar]

I just received my new miniPRO from amazon and am feeling a slight grinding in the platform.
It does it mainly when I am traveling at low speeds, once I get above about 2 to 3 mph the grinding stops completely.
It just feels like the gears turning between the motor and the wheels.
Is this normal or should I be contacting support about this issue?

Thank you for any help you can provide.
