Fellow rocketeers tend to hate the old copperheads for their poor reliability. I found that if you just treat them gently, they work quite well. At my local club where it is usually quick and easy to change out an ignitor, I will usually start with the copperhead that is included with the reload. It would be too expensive to throw out the copperhead and use a First Fire in every motor. However, when I am at a big event and want the best reliability in my E-G motors, I will pull out the First Fire Jr. Nothing worse than waiting 30-45 min for the launch cycle and then have your ignitor fail. I have yet to have a properly First Fire Jr fail to light my motor. Well named.

I recently launched a 29mm SU on these ignitors, and could not be more pleased. I used a 6V system, yes that is correct. You can use the standard Estes control for these, knowing this saved me a ton of money in the long run. They do take a delay to fire, but so do all others. The only con is the price, 3 for $8 is a bit expensive, but for how well they work, I will take these anyday.

I've used at least two or three of these in my rockets, all of which just wouldn't light with the copperheads. On all occasions, these lit up the motors first time every time. These are really great, so much easier and more reliable than the copperheads. Supposedly, Aerotech caught on to this, and has discontinued using copperheads in the reloads, but there will still be many still in circulation. These are really, really awesome ignitors, and the only downside is that they're usually pretty expensive, usually Between $8 and $12 for three. Expensive, but worth it!
