Rocky Mountain Radar RMR-C435 Review

Think Twice

The RMR-C435 is affordable and features a lot of extras, like VG-2 and VG-3 Immunity that shield the detector from police devices designed to spot the detector, and a laser scrambler. Many users insist the detector doesn't work, that it has problems with the X, K, and KA bands and the jamming and scrambling features don't do their jobs.

It looks appealing on paper, but Rocky Mountain Radar RMR-C435 reviews say it deliversless than it promises. This model features a laser scrambler that's supposed to scramble all laser and regular radar bands and VG-2 and VG-3 immunity that's supposed to keep the unit hidden from police radar-detector detectors. An expert radar detectors review on Radar Busters, however, asserts that laser scramblers just don't do what manufacturers say they can do. Some users agree, and in reviews on sites like Buzzillions they add that the featured immunity is weak, as well. Drivers report getting pulled over at speed traps because the unit didn't send an alert, although such failures seem to be more common with older units. Drivers posting reviews on Cabela's likewise grouse about the unit missing its mark and getting hit with tickets as a result. Users also say the audio alert is too soft and false alarms relatively frequent, especially for the X band. Nonetheless, we read reviews posted by consumers who are satisfied with its performance because it \staved off the ticket police numerous times.

In addition to the scrambling and immunity features, the Rocky Mountain Radar RMR-C435 (starting at $125, Amazon) also offers four levels of dimming on the display, city and highway mode, mute, 360-degree coverage, three-year warranty, and a one-year ticket rebate program.

Although the manufacturer is willing to support the product with an offer to reimburse you for fines attached to speeding tickets during the first year of ownership, we're not convinced. We came across too many negative reports about the reliability of the scrambler and the sensitivity of the unit in general, and drivers groaning about the tickets they received.  You might want to speed past this one.
