Title: Complete garbage
Review: I've used Estes solid propellant rockets for over 25 years and have always been a fan of the product. But the hydrogen rocket is complete garbage. I've tried it numerous times, following the instructions precisely, and it completely fails to operate. Estes should provide more trouble-shooting information (that really works), pull the product from the market, or offer refunds for it. It's junk!
