The controller fell about two feet from a small one and broke two sticks. It made everything moot. Everyone was really looking forward to being able to fly for a while but never managed to get the batteries into the controller which made it a bit heavy and could fall off small hands. It was an accident and he must have hit just the right spot to break both holds at the same time. I used very strong glue but to no avail. It just shouldn't have happened. It appears to be a well thought out and constructed drone and I was impressed with all of its features and the drone itself with a prop guard and two power packs that slide out for a quick spin. Also came with an extra propeller. I'm not deducting any stars as it's well made and well protected in a good case and this is due to operator error but it seems like there might just be a weak spot on the buttons on the controller which may need to be a bit thicker or other small changes so that a small drop is not a disaster and temporarily grounds the drone until a new one can be found. Four stars βοΈβοΈβοΈβοΈ!
