No customer support for non-functional parts
For DIY Line Tracking Smart Car
I wrote the seller with concern that the unit did not work. We have a bad LED that will not light up. There is 1.3V at the LED but no light. Being one of the two LEDs for the photo-resistors, it is functional not a cosmetic light so the unit will not work at all, just goes in circles.
It's been 4 weeks and we received NO RESPONSE AT ALL!
