The package was received very quickly in Canada (approximately 10 days). The mother card arrived in perfect condition and no problems when installing it in my Segway Ninebot Mini Pro (video available on youtube). Then you have to recalibrate the Segway and then disable the 10km speed limit. Once it is done, the speed is unlocked and there is no more sound during the 16 km/h pass. I managed to drive at more than 23 km/h without difficulty. I am really very satisfied with this purchase and I would like to highly recommend this seller. (I was also able to use the Android app without it raising the speed limit to 16.5km/h but don't do an update)Thank you very much
worked great... my son had rode through puddles on his minipro. I was hoping it was the motherboard that was causing a short. it turns out I was right. this worked great (and its faster) the only issue that I encountered is that i had to recalibrate the minipro (turn it over, press the power button and it does it thing.) I also had to reinstall the app .. but it works!
