Hello, I recently bought P3 Pro on eBay from a seller with mostly positive comments. Their price was unbeatable. After the first flight I noticed that the shots from the camera are blurry or out of focus - I have another thread about it. After reading a lot on the internet I am coming to the conclusion that I have received a previously used unit. Possibly somebody saw the quality of the camera, returned it and now I got it. Can somebody confirm if any of the below can suggest that it was previously used: No protective film on the lens. Battery and controller already charged (my friend got one and the controller was completely without any juice and battery just one bar). Already activated with DJI? The initial activation never came up. Firmware already updated (my friend got one around the same time and his firmware was 1.4, mine was 1.6). Thanks!
