Ater 2 months of utilization I connect my power meter in the app and he asked for a firmware update 3.92. After that he stops to work and I tried to contact the warranty, without many answers the SIGEYI request to me to sent the power meter back to China with no refund of ship charges and only after that they will send me a new one. Warranty services is a shame.
I don’t recommend the product. Pay a little bit more and buy a quality product avoiding headaches.
