    Moved from an Escort Ix to this R4 and wow, it is really amazing. No false alerts. No blind spots alerts from Hondas or tahoes. Almost completely silent.

    Bought this for my 22 WRX. Have the R3 in my wife's forester XT. Best detectors on the market, saved us multiple times. R4 has much better range, but can't go wrong with either one. Highly recommend to anyone skipping for either.

    Good detector without arrows

    Posted .
    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.
