Review on Frostory Car Reverse Backup Parking Sensor Radar System - Waterproof Sensors, Detection Distance: 30~150CM, Buzzer Beeps - 4 Packs X60D (Silver) by Brian Page

I have a red Rav4 and these sensors color match almost perfectly. I'm very happy with how they look. Also the included hole saw was able to make the perfect hole for the sensors. If you can remove the bumper, installation is pretty easy. I wish the cables were a little longer. With an SUV like mine, cable length becomes an issue. They're also great for reverse or parallel parking, but aren't as good at pulling out of a spot and spotting oncoming vehicles when reversing. My wife's car has factory reversing sensors which are much better at detecting cars moving perpendicular to you when reversing. These sensors rarely detect cars approaching me. I'm not sure if it can't measure fast moving cars or something like that.
