Holy Stone HS720R Drone has been flown 2 times, a total of 6 minutes of flight. A terrifying 6 minutes, circling faster and faster, but has never been crashed or even landed hard. This has built in Standard remote ID so no need for a module and spec wise it's a winner: 3 Axis Gimbal, GPS, 4K, EIS, 10000 Feet Video Transmission Control Range, Brushless Motor, Follow Me, Auto Return, the works. The problem is that if you live anywhere near the Bermuda Triangle magnetic influence (or many other places) it has a tendency to "Toilet Bowl" for me. It can be brought under control by flipping to the fastest speed (switch to right) and showing off your piloting skills by guiding it safely to the landing pad. I did this exactly twice with this exact drone, but my nerves couldn't take it anymore, and you can see my flight here https://youtu.be/IFWEJDSladU?si=JLaTI233jYLWS021 . Now, some smart alecks tell me that I didn't calibrate it right, or do a Gyro calibration, or spun it in the wrong direction, or didn't stand up straight, or whatever. If that's the case, my ignorance is your gain. I'm also told that depending where you live it will work perfectly and not spin at all, but apparently I'm not that lucky. So, if you live in one of these "exempt" magnetic pole zones, it may fly PERFECTLY for you, and in this case it will be a bonus for you. HOWEVER, this is being priced and sold as "extra parts" if you will, assuming you have a drone like this and you just want the extra batteries, props, remote and stuff. If you try and fly it that's up to you, it is complete and like brand new, but in good conscience I can't recommend flying this because of my poor experience with the THREE of these (yes, I tested 3, and they all flew the same, hence, maybe it IS my area...). As mentioned, it does come with 3 batteries which are $89 ea. so these alone are worth the price. It also comes with the drone, remote, extra props, cables and a custom case. So, you could end up with a great flyer for REALLY CHEAP, you can part this out yourself and make money, or get a really good deal on spare parts for yourself, your call... I can't imagine anyone who would want to return such a cheap box of parts that is a piece of history that could circle all day long with so little effort, practically orbiting by itself (actually it did orbit by itself). Hummingbirds are mesmerized by the circling I'm told hummingbirds mate for life, so this drone is absolutely not returnable once purchased.  The hummingbirds in the area would fall into a deep depression and we can't have that.  Seriously, don't even think about it.  And if you are, you can't buy this drone.  Move along, nothing to see here...  If you do buy this and decide to fly it, you HAVE to comment on my YouTube Channel (link of video above) and let me know that it works for you. That's the rule. Since this is $550 new with the extra batteries and could get it for the price here, and it works for you, you should consider playing the lotto too!
