I sent my 9500i back to Escort to have it upgraded to a 9500ix. Turnaround time was very quick, and I got back what appears to be a brand new 9500ix. I have three radar guns and tested each of them....Bushnell quick trigger......no response. Kustom Falcon K band....instant on, full second delay before the detector alerts. Decatur Genesis Handheld K band, same thing. I'm having buyers remorse, as this thing could have been dumped for $300.00 on Feebay and I could have picked up an STI-R Plus for only $700.00 more.
