The price was too good to miss.
Off the bat, I can see how long Valentine 1 came over the years. The older unit is a few ounces heavier than my 1.8. I'm guessing the newer hardware got more compact with the year, not only the 1.7 is heavier, but thicker as well.
The programming is a bit different, there are different options.
The speaker is a bit worn out.
The laser sensor is underneath the rear radar antenna.
The unit also does not work with the hardwire kit, but I knew that.
I took the regular power adapter so I can test it.
The unit works fine for K and X band. Haven't got a chance to test Ka yet.
I will most likely send it for an upgrade (a new unit) soon.
Just thought I'd share. Comments/Suggestions welcomed!
