Holy Stone Drone set of 2

One drone works perfectly, only used a few times. The 2nd drone has either a propeller issue or an issue with one motor, i am not sure so i am including it as for parts. I have not used it for about a year, not sure how good the batteries are but they are easily replaceable and i turned one of them on as in the video and it shows 75% full considering that i didnt even charge them for over a year. These are very good expensive drones.
