Bests & Worsts Reviews from Amazon

I had this drone for over a month with no issues until today. I headed to the lake. I turned the spark & remote on connected to the App and set the home point and took off and took several photos. I brought it back home without issue and changed the battery out for a new one. I set the home point took off circled around and had it hovering about 15feet away ready to take off and then it just dropped out of the sky and in to the lake. No warnings, no nothing. The battery was at 90% and everything was working as it should. The drone just seemed to turn off and fall from the sky. I have since googled the issue and it seems this has been happening to others, unfortunately for me it happened over a lake and the drone is now lost. I'm unhappy to say the least and $500 out of pocket not to mention the 128gig Micro Sd card that was also lost.
