After 2 years of using the D1X version one, it stopped working; so I shipped it out to Archer to see if it could be repaired. They unfortunately informed me that they are going out of business and no longer supported repairs of the version one. They offered me a used, but fully functioning version two. I only had to pay for the battery and charger. It was a great deal for me and I just received it and installed it. I would like to thank the Archer team. I'm sorry that you are closing your doors.
