Bought for my son's birthday. he was very excited. Let me tell you this thing can fly! Really fly! The lights are amazing, you can see them from over 3 miles away! I figured there would be enough space at the local park to fly it. However, we pressed the start button and it disappeared. I swear that thing goes 30 miles an hour! When we chased it in our car, the battery life easily lasted 10 minutes before the lights went out. On our local Facebook page, people reported that it passed overhead about 4 miles from where we were. Unfortunately we never saw him again. My son was very upset, his birthday present flew away.
