If you are looking for one of the most compact and highest performing units, then go with the Radenso Pro M. However, the Escort Redline EX is a way better build quality and has much better laser performance and automated features such as the automatic screen brightness and false frequency filter

Performance seemed adequate overall (e.g. filters vs fans alerts)

I own all of the top detectors and the R-
