I had both the Sensor and React. I like both radios but I just couldn't drive very well with the React as the spring tension on the steering wheel was just not tight enough for me.

I like the Sensor best of the two and the large screen makes for easy reading at a quick glance. The only thing I wished was it had more memory and could switch from Nomadio Transceivers to DSM without needing to use the laptop all the time. Only other thing I would of liked to see what a charge jack which I think could of been a running change as I think they can do it pretty easily.

All in all never had any problems with them and would think of a Sensor down the road if a few changes where made. For now I will stick to my 3PK but like I said nothing bad to say about Nomadio as I would buy another one if I came across a good deal. Overall very nice radios.
