    Received in short time.very pleased with it.
    EVELYN -- dorchester, SC   3/7/2013
    I returned this sensor, read previous review.
    Tom -- reading , PA   12/2/2012
    Sensors have limited tilt ability and must be set virtually straight on. Followed instructions to the letter and tried all available sensitivity settings. Picks up foot traffic most of the time in it's range, but not always...about 3 out of 5 walking through the beam are detected. Quick moving vehicles coming up the driveway 10 to 15mph...Not at all...Not one!
    ELYCE -- jamesville, VA   11/8/2012
    Very pleased , installation easy, works great, customer service very helpful.

    JANINE -- new bedford, MA   1/19/2012
    a must have for piece of mind.
    JAY -- wilmington, NC   1/5/2012
    Great way to know when someone enters my property. False alarms happen sometimes too often.
    WAYNE -- wallace, NE   11/14/2011
    love the add on sensor as it gives me notice when someone is coming in the back way.
    JOHN -- boise, ID   10/7/2011
    very good range & sensativity
    PAUL -- greeneville, TN   9/16/2011
    we have four sensors and have no problems with any of them.
    ELAINE -- prince albert, SK   8/11/2011
    Synced beautifully with the main set. We have three sensors, and the different sounding alarms for each site works perfect. What an inexpensive way to a little piece of mind!
    MICHAEL -- souris, PE   6/9/2011
    An excellent product. One works great at the end of a 300 ft drive, and a second serves as an "automatic doorbell"....
    ROBERT J -- ellenton, FL   6/9/2011
    Great Alert System, we use this at our cottage as the entrance is 300 yards from our home. This lets us know in advance of someone arriving
    RYAN -- hogansburg, NY   4/16/2011
    works good!
    ROBERT -- guerneville, CA   4/11/2011
    this product is extreamly cheep and i dont mean inexpensive. The detection is spotty and unreliable the quality is Poor and the the product has little flexibility
    DANIEL -- oak hill, VA   3/24/2011
    A wonderfully flexible and affordable it.
    RUSSELL -- delta, BC   3/17/2011
    I have used the "Reporter" system for about 8 years now. I needed a replacement for one of my 4 units I use on my residnetial property. I find them to be accurate most of the time, the odd time there is a false report from a Racoon, but in general I recommend them highly as an inexpensive security device!
