I would like to see an improvement in shipping because it got delayed twice
Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
Everything is very explicit, .... commom knowledge. Connectivity very easy and app also no problem. Engine responds very well, no alterations registered for the moment. Sure to be recommended.
Everything is working fine.
