    This detector has everything you need to save your bottom. None of the extra nonsense of the higher priced models. Definitely recommended. If you avoid one ticket it pays for itself.

    The plastic body is poor quality for the price paid. The unit does work well.

    So far so good. Paired it with the R4 Companion app which adds more capability. Able to detect radar at very solid distances.

    Good detector without arrows

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I have Uniden R1 I thought about buying an R8 but decided that I could live without the arrows not to mention the R8 cost 699 versus the 379.00 that I paid directly to uniden. I missed the previous sale that bestbuy had on it. Overall a good detector and filters blind spot monitors out pretty good. But keep in mind that if the cops are using laser for detection and hits your car and you're speeding youre toast the detector will let you know that you may be getting a ticket. But against all other speed detection methods it will warn you along way down the road. It was worth it to me combine with waze it can be almost as good as using a laser jammer.
