This is my first drone. I found it very easy to set up and use, very intuitive and the app is great. The photos are also of pretty good quality. I got my D80 about two weeks ago and just two days ago it was flying normally for about 10 minutes and suddenly it started diving at high speed and crashed into my pool quite hard. deck and then jumped into the pool. It was properly calibrated, so we're not sure what happened. I contacted Potensic customer service and received a response within 12 hours. They accept returns and refunds or replacements. They weren't sure if magnetic interference or a malfunction was the cause of the problem. I was impressed with their customer service and commitment to supporting their product. Out of curiosity I connected the battery to the drone (both went into my pool and the drone got damaged) and this damn thing popped up with all the normal sounds and lights, this thing is built like a tank! I have enjoyed flying the D80 and reading the reviews of their earlier and more basic models and they have all been great. , so I decided to replace my D80, the quickest way was to get a refund and order a new one, so I did! My replacement is coming tomorrow!
