    Product as described. Works well so far
    NICOLE -- st. albert, AB   11/26/2013
    I am very happy with this door alert system. It took about 15 mins to install and is working perfectly. The service was great as I received the product a few days after ordering it. I would recommend this company to other people.
    M HEATH -- raleigh, NC   11/29/2012
    Easier to install (and get the sensor beam lined up) than I expected. Doesn't recognize fast-moving traffic (i.e. I walk fast and it often doesn't ding for me).
    PAUL -- cerritos, CA   7/26/2012
    I use mine to warn if someone has entered my garage when the door is open. My only problem was that the wires were not long enough to allow me to install the siren inside the inner door to my house where I'd be sure to hear it from anywhere in my house. I happened to have a mimi-plug extension and that solved that. Overall, excellent.
    KENDALL -- san jose, CA   7/2/2012
    Product works very well. We set out up to warn when someone enters thru garage door when it's open. Every once in a while it will not recognize the beam has been broken.
    ANGIE -- grande prairie, AB   5/30/2012
    Excellent Product! Does what it needs to do without a lot of bells and whistles! - We have a small business and couldn't find locally any product that worked for our application. Extremely easy setup - in fact we bought 2! Would shop with Smarthome again - well packaged and quick delivery! Thanks! From Alberta, CANADA
    DHARMESH -- eastover, SC   5/28/2012

    DOUGLAS -- wheatfield, NY   5/12/2012
    Easy install and easy to use
    DAVID -- alexandria, VA   3/15/2012
    Solid product, I recomend it.
    MARK -- mattoon, IL   2/23/2012
    Great product!
    AL -- wilmington, DE   2/9/2012
    It is absolutely the best we could have expected. Very nice rugged piece of equipment. I highly recommend it.
    CHAD -- napa, CA   12/18/2011
    Works perfect. We have the sensor on the door in one room and the speaker in a back room for security purposes. The wires are good lengths too.
    AMBER -- cleveland, OH   11/11/2011
    Easy to set up, loud enough to hear in the back of the store and very unobtrusive.
    VACUUM -- taylors, SC   10/16/2011
    Have looked for and bought many entry alert products. This is the first that has done what it promised and is reliable. The price was great also.
    HECTOR -- miami, FL   9/8/2011
    Good item!!!
    DOUGLAS -- port saint lucie, XX   8/4/2011
    this product works as expected so far no problems. does what it is we intended it to do..simple and very easy to use installion was simple...
    FERENC -- kenner, LA   7/2/2011
    Product arrived on time, and with all needed parts in the box, installation was easy, though alignment a bit more challenging. A visible lightbeam during aligment would be extremely helpful. In a location exposed to outside temperatures, it is far superior to IR motion sensors.
    FORREST -- lakewood, WA   5/21/2011
    Works great and very easy to set up and use. Beats my old battery powered system and can be turned on/off at will. I do think the volumn could be a little louder when turned all the way up but still works good. Thanks
    SAM -- honolulu, HI   5/18/2011
    Worked perfectly out of the box with minimal setup. Reliable and plenty loud!
