Pros: Support! I have contacted Tomzon support and I want to let you know that the support is fantastic! They solved my problem very quickly. It's pretty easy to get airborne - once you know how. Very stable and easy to fly. , the recorded video is made only on the phone. The range is limited - only about 100m of the real world before the video stream is interrupted and you are forced to press the "Return to Base" button. The instructions were pretty clear. - except trying to figure out how to do the initial calibration. We had to watch a few videos online to figure out that you rotate the device, then make sure the camera is facing up as you rotate it around the axis again. We still can't figure out how to save the photos and videos we take. Also, there is a lot of duplication between the phone screen and the controller. I'm still not sure if the antenna on the remote does anything (because I think you're connected to your phone over Wi-Fi to control it). A good training drone for the price and recommended.
