Actually, the X-Star series was released in April of 2016, so it has been about 1.5 years. They also did not have serious issues like the Solo. They most certainly slowed their progress but they do have promising products coming to market... very slowly

. The new firmware has certainly improved it immensely. I think one of the biggest benefits of owning an Autel is their US based customer service that answers the phone 7 days a week and the excellent service they provide.
I do like the X-Star but DJI is the king and will be until someone can topple them.
