Awesome customer service

I had a rocket engine fail to launch. It just detonated and destroyed my Cherokee e rocket. I sent an email with questions regarding the motor failure and Estes without hesitation replaced the motors and not only did they send me a replacement rocket they sent me an upgrade. Thanks
