I purchased two of the Nano Copter Mini Helicopters, unfortunately one was not working properly so it was returned for credit. The one that works is really so much fun to fly. My intentions was to give it to my 8 year old cousin but I have so much fun with it that I kept it for myself instead, and I am over 50 years of age. I wouldve given 5 star but was disappointed with receiving one with the defect. Customer service was very kind and I was given cedit.They will give back your fee if you are dissatisfied with an item. I still order items from you and most of them have been great and will continue to check out items of interest to me. Thanks guys!
