I was having problems with my Gempro 250. On Oct 11 I sent it back to the company for warranty repair. I sent it Priority Mail. According to the tracking number it made it to Phoenix AZ by the 14th. It went out for delivery on the 14th to the company but has not been delivered yet. I called the company 2 times to see if it was delivered yet and was told they didn't get it. I was prepared to start making phone calls to the post office to try to track it down. But I didn't have to. The girl on the phone said that they will ship me a new one. I was amazed that she just said don't worry I will send you a new one. One of the best customer service policies I had ever experienced.
