I saw one 3years ago. Home inspector was using p4p to inspect roof on house I was selling. Needles to say I fell in love. I asked him if it could go to my father in laws house about a mile away? He took off in sport took pics of FIL swimming in pool and pressed return to home. WOW!
Now I have one but isn't what I expected with so much tech to learn and hidden costs. Oh well maybe it will get better with cash and education.
