Estes 2230 E Launch Controller, Blue

If your controller doesn't work try trimming about 30% (and up to 50%) off the rubber stopper on the key. The key can then be inserted that much further to make its connection. I had to do this to what was an very dead controller and now works a treat.

Very well made, good quality product.

It doesn’t work. This seller appears to be a scam-artist.

Made well. Item works great

This launch controller does not work at all will not reccomend buying it.No wonder the quality is so bad.
