Placed order 11-26-25, finally received 12-30-25. Didn’t know it was a back ordered item. Customer service was helpful but it was frustrating to wait that long.
Item works but the radio plug doesn’t stay in so I had to make a retainer
I bought these for my Grandaughter who has her private Pilots license since she was 16. She is a Freshman in college studying Aviation. She was so excited to get them and just loves them!!
