Query: mediocre performance and false laser alerts in sunlight

I have used a Valentine unit for years and been very happy with its performance but needing a unit for a second car decided to opt for the much cheaper Beltronics RX65 radar detector. I found that in terms of Ka band detection it was mediocre at best and provided about 1/3 the distance that the Valentine provides at various speed metering locations in the area.Worse though is the units false laser alerts that go on continuously whenever I drive toward the sun early or late in the day - i.e. commute hours. The only fix is to turn the unit off.This is really a terrible value and a waste of money.
