My last RD (Cobra), went belly up after only about 1.5 years of use. Not sure why, but it makes me wonder if RD's only have a certain lifespan before they start to fail...which also makes me wonder if it is safe to buy a used RD off various sites?
Other than the cost difference, how exactly do the Red versus Blue differ. Is that it...just different color LEDs?
What is the deal with the various versions. I don't see most folks selling this model to list the Rev. or software version, so how important is it.
Finally, I am looking for a good quality RD. Is this a good solid unit and as good as I need? I want one that is able to detect the latest technology...does this do this?
Anyway, just wondering about a few key points for this unit.
