Every problem I have ever read about concerning this has to do with the individual not being able to read the display size of font. The newer remotes like the TX915 that goes with the Inferno, Banshee, and Screaming Banshee have a larger display and are just naturally easier to read. I don't do any night hunting, but when I field tested the Firestorm with the TX9, I had no problem reading the display at any time of day, even in near dark conditions. I have never had any problem reading any of the displays on any of the remotes, and I wear bifocals. Obviously, a person's vision and ability to read smaller print vary from person to person.
If you were treated rude, I am totally surprised. I have never heard of that happening before.
