I couldn't be much happier with this unit. Where it really shines is in battery life. I've used this in various 4x4 competitions and my teammates use some much larger, clunky handhelds that require 10 batteries and eat them up quick (several sets in a weekend). I use 6 nicads in my midland unit and they last and last.
Its a pretty decent mobile unit too with the adapter. With an external antenna the range is tremendously improved. My only real complaint is that I wish that there was a way to lock the backlighting on when using the car adapter - this would make it easier to use at night.
