I have had my ProM back now for a few months and I honestly haven't had a chance to run it since I ride most days. But I took it with for 1400 miles last week. I like my short reviews straight to the point thoughts so, it's good. The ProM is wicked quiet out of those 1400 miles the only falses I had were from CTS' and CX5's and that's it period. The times I did need it the range was plenty to slow down. Did I mention it's tiny? I love that. No big hunk of CM hanging off the windshield just a neat little package that gets the job done. It's got bells and whistles if you like that too, to me it is meh since I drive rural but those bells were awfully nice to have rolling through cities. All in all it does a great job and I think it is a fantastic detector. Settings for the 1400 miles were latest firmware(update before I left) Highway/GPS on//Ka Wide//Ka filter on//K narrow//K filter high// everything else off This wasn't a detection but I did capture the only laser from an Iowa State Patrol on my trip. Looked like a TruSpeed or Dragon Compact. From what I could tell it was small, thin, and vertical lenses.
