Query: another life saver

brought this for my disabled son his other one broke. was really nervous about refurbished item, i never brought refurbished and knew that if i gave it to him and it did not work he would be unable to understand and think i was mean. but i thank amazon and seller for making my son happy he really loves the silver color the other ones(about 30 or more in his 15 years) were all black. looked alittle used but the works great. he looked at me like a was the best person in the world for getting this for him. thank you amazon. also remote works great no batteries so please make sure you have them. son gave it 3 claps and a spin.
