I ordered mine the day uAvionix released them. Install was a bit longer because the builder of my plane bonded the tail light in the rudder, and didn't leave any spare wire. So I had to fish new wire through the rudder. Total was about 4 hours time. Wired up, set up on the app, and went for a ride. Received a near perfect report by the time I got home. Then a few months later when the FAA brought back the rebate program and experimental planes weren't eligible uAvionix brought out their own $150.00 rebate. So I emailed asking if I was eligible for the rebate since I bought early they said sure, and sent me the gift card. Very pleased with the product and the company. Over a year now and no issues.
