Review on 🚗 Frostory Car Reverse Backup Parking Sensor Radar System - Waterproof, 4 Packs X60D (White) by Jorge Eckstein

I have mixed feelings about this set. Build quality is cheap, but I wasn't expecting much. Functionally, it worked brilliantly for several weeks, and then suddenly it started false alarming - detecting apparent obstacles that just weren't there. I installed this on a convertible which is a little difficult to fit (because of the small plastic rear window). I was fine with that until that false alarm kicked in. I disabled the sensors one by one and found that only one of them is causing the problem. At some point I will probably try to replace just this sensor, but I came across a nice "feature" while troubleshooting. The brain unit seems to run a self-test every time you put it in reverse. If it detects a disabled sensor it will emit short beeps - I believe this is on purpose to alert the driver that the system is not working properly. I did not expect this complexity from a very cheap kit. In any case, after three "warning" beeps, the thing works fine, albeit with reduced range. I can try to contact the seller to see if they can guarantee the item. Until then it's a 3 star rating.
