We mounted both detectors on the M3's windshield side-by-side for three months of highway testing. One suction cup left, one right. Same road, same threats, same Wisconsin winter. The Uniden R8 alerted earlier and complained less. The Escort Max 360c costs $150 more and adds directional arrows. That's the entire difference. If you need to know which lane the radar is in, buy the Escort. If you want more warning time and fewer false alerts, the R8 wins.
