So far, so good.
The GPS works accurately. It is a style, but I notice some inaccurate measurements, such as the steps and the height. Furthermore, it is very sensitive to the handle movement, energizing the throttle with a slight movement of the handle. I don't know how much epoxy is in the nail polish. The parallel was at 90% brightness and in one day it went down to 80%. I will fix it. 50€ is not much, but for the left side it is good because there is GPS.
