What is Reddit's opinion of Estes 2230 E Launch Controller , Blue?

From 3.5 billion Reddit comments

So I buy them off Amazon, but used to get them from hobby shops. If you just look up " model rocket engine" it'll have quite a few come up. You'll see engines ranging from a to e. A is the smallest, launching a few hundred feet. E is the largest, up to about 2,000 feet. They will come with different sizes, add if you get a kit, it'll tell you which size to get. To ignite, I use an Estes remote. Here's a link to one of them.

Model rocket ignition system. 30' corded. Works well.

Edit: you will need ignitors as well.
