“Ain’t no shame in the oldies, I’ve since upgraded but Dad’s still running a DFR7 from 10+ years ago with no plan to upgrade. Not the fanciest thing any more but works like a charm!”

Top Criticism

+2 pts

“This would be my suggestion as well. Prices are up across the board, Cedar recently even increased the price of the refurb. Uniden has the DFR7, a 10 year old detector, for $225 (woof!). Somebody might be selling a new or open box 700i in the $150 range. Pair it with the Drive Smarter app and they'll be in decent shape.”
