I've been using a Sensor for two years now and I think it is one of the best radios out there. I drive left handed and when I went to search for a new radio, having the ability to run it left handed was a major consideration. Nomadio fans are a very loyal group of drivers and all will tell you their radios are excellent.
There are some issues with the steering wheel shaft being somewhat brittle if you reef on the steering wheel a lot but there is a guy that makes turned aluminum replacements that are simply awesome. All this info can been read on Nomadio's site forum.
Bottom line; it's a great radio.
