About 9 months of use now and this thing has been great. It has a mode that will allow you to see multiple radar sources at once. Very accurate and few false alarms. If there is radar present it will alert you. Great range of options in the settings, just make sure you read the manual and keep it handy for future adjustments and fine tuning. A bit on the pricy side, but it will save you if you have a heavy foot or if you are in the wrong place at the right time.
