Electron Beam Model Rocket Launch Controller

I have used this product launching at least 100 rockets now with a group of Cub Scouts in my Den and have not had issues with launches. As another person wrote, the safety button was tough to hold down for a young person, but after about 15 uses it seemed to soften the rubber on the safety pin and it worked fine for ages 8-13 yrs.

This is a capable enough launcher. It has a key you have to insert as a safety precaution but it takes quite a bit of force to hold it down. The bulb that indicates that the circuit is armed can be difficult to see in bright sunlight. Overall, this isn't fancy but it will get the job done.

Have had it 4 years, lost it in a field for a month once, rained during that time, found it later on, still works great!!!
