First of all my son would rate this item 10 stars out of 5 if he could. He played with it every day for a week. I would say the total playing time is around 10 hours at the moment. I definitely need another battery because it breaks his heart when he dies and I have to charge it. With all of this, no problems arose over time that would raise questions about the build quality. I still have 4 original propellers connected to the drone, none are broken or chipped. They also give you 4 extra backup props just in case. The drone itself is well built and has survived a full speed wall collision many times. My son loves the flip feature that allows him to automatically spin it in the air. He thinks he can do the trick and is constantly trying new ways to launch the drone into and out of objects. In addition, the emerging drone has practical applications. I had to check the gutters to see if they needed cleaning. So instead of taking a ladder and moving them around the house six times to check them out, I just used a drone and an app to see what they looked like. It was very convenient and saved me from a Saturday afternoon. The controller itself is well built and has enough power for 2.5 flying battery charges before needing to be recharged. The control sticks offer solid resistance and allow for fine-tuned maneuvers with the drone. This is a great toy or even a tool that you can use. The price is great, the build quality is great, the controller/accessories are great. Highly recommended for purchase.
