This was very easy. All I did was plug it in. It let you know is the a police in the area. And also remember the police radar are off and they get triggered if a vehicle is traveling at a high speed. So far it has work great for me. I really like it. And I am glad I got it.

[This review was collected as part of a promotion.] Nice, small and easy to set up device. I think the range might not be the highest out there, but it seems adequate without going to devices that cost twice as much.

[This review was collected as part of a promotion.] Radar works extremely good. Was able to see a Texas State Trooper in the darkness of night with almost a 1.5 mile distance to close. Gave ample time to slow down.

[This review was collected as part of a promotion.] Going to buy one for my stepson. I love mine

[This review was collected as part of a promotion.] this works very well, its also easy to use and understand

Modern features make this the best radar detector I’ve ever owned…I’m very impressed by the distance covered…many features…I’m still learning though the default settings are best choices for me…I like it…

Instructions are very clear and detector is easy to use. This one is much better than anything Cobra offers. The name fits as it does detect at a long distance.

It works great !!!! I didn't realize how many cops I drive by until I got this detector, and what's even better it gives you a long range warning.

[This review was collected as part of a promotion.] For the price, it is a decent unit. There were some others I would have preferred, but due to time constraints, price, and availability, it seems to do a good job. The price was reduced to $299 ($100 off), but delivery was available within 24 hours. I have no regrets, but there were some other units with a few other options available, which I would have liked, such as wifi for updates. This would have been a 5-star detector 10-15 years ago at $499, but for the price and its options, it is a solid 4-star. I can note that the false alarms are minimal. I ignored one at 5 miles over and received a warning. So, for that reason and several others, you can have a reasonable expectation, even with instant on, that there is a radar or laser in the vicinity.

after reviewing the different type of radar detectors, I think the R7 is a better deal and a better quality radar detector
