I *did* own a Unmanned Aerial Vehicle... I will not name the manufacturer - it is one of the top sellers in the US... for about 20 days. I spend $1,300 for it, spare battery pack, spare propellers and a nice (hard) case.
I read the manual several times and followed the instructions. GPS lock/6+ satellites, green light on the UAV, safe use guidelines, did not fly in an area with power lines (above or under ground) or other radio interference (I could see only 2 weak wifi signals on my iPhone waling the perimeter of the place I normally flew), did not fly over people... all the "correct use" rules/guidelines.
After 5 successful and uneventful flight sessions, on my 6th session, flying at about 200 feet up, I decided to fly close to the ground... perhaps 2 feet. Ath this height, the UAV was no more than 70 feet away from me (and the controller). This place is an open field, about 70 yards long and 35 yards wide, surrounded by an "open" rail/fence... basically, a horse arena (no horse, no people - except me). After about 2 minutes at about 2 feet off the ground, I had the UAV hover. The motors got louder and seemed to be going faster... then the UAV flew away all by itself... into one of the wood rail fence poles.
Two broken propellers, broken safety bumpers, and the battery popped out. Everything else was fine - including the camera. The props were replaced, the battery re-inserted and the safety bumpers repaired with tape. I re-GPS'd until the UAV had green lights, verified all was in working order (including the camera) and re-identified "home". All was in working condition.
After verifying everything was working, the UAV was landed, powered down, disassembled for transport, packed in its nice case and I went home. And I searched "______ (manufacturer's name) flyaway". It turns out these things take off on their own.
I did not want the liability of injuring someone or something because of something I owned and was responsible for - but had no control over (the manufacturer very rarely admits device fault).
I did not want the potential responsibility of causing damage to property due to something I owned and was responsible for... If the UAV had been 200 feet up and took off on its own - with a 10 minute flight time it could have easily reached a rather major road - even a freeway - and crashed into a car being driven. The battery could have popped out, somehow caused a short and started a fire. The UAV could have crashed into someone's house or through a window. Any number of potential emergencies could be caused... And I would be liable. So my (homeowner's) insurance had better cover that "accident".
I contacted the retailer - they let me return the UAV because it was within 30 days of purchase and I received full credit on my credit card... even for the broken propellers (I expected to at least pay for those and the safety bumpers, but the retailer said they would credit the entire purchase). Basically no questions asked and full purchase refund - they also paid the return shipping charges. It seems they get a lot of calls about UAV flyaways, but if the UAV is gone, they cannot issue a credit, so I was fortunate.
In the last two weeks, a hyper-local neighbor site has posts from several folks finding drones on their roofs.
To answer your question: I did own a drone.
Will I get another one? Not until I have more assurance that I won't see my investment fly away on it's own. At this point, I have not seen the various manufacturers step up to take any responsibility... It continues to nearly always be "user error". And that means end-user liability and responsibility for a potentially defective device that can be a huge safety issue. And even if it is 10% flyaway for whatever reason, that is too much risk for me.
Please keep in mind that these are the low-end UAVs that use shared radio frequencies - mostly anything under about $3,000. I expect licensed frequencies and professional grade models to have a much lower incidence of flyaways and they may be worth a look when their prices are in the $5,000 range.
