I just bought this M-20 unit last month... and now I am reading that it doesnt' even work correctly. I spoke to NY state troopers and they told me that they are useless against the new emerging technologies.
Should I just sell the unit and wait until something better comes out? Blinder most likely may not offer an upgrade for free... so it might be worth it to sell + rebuy later?
I seek your advice. Thanks ops:
