    ROBERT W -- east troy, WI   12/30/2012
    Works as advertised. Installation instructions could be a little clearer.
    T PATRICK -- houston, TX   12/21/2012
    Controller did not perform on every test. Very disappointed with all of these good made in CHINA, seems like nowadays I WASTE a lot of time and money replacing units that only last a fraction of their service life. What a disappointment.
    MELLET -- montral, QC   3/4/2012
    Works perfect, easy to install
    RANDALL -- saint paul, MN   11/4/2011
    Works as advertised. Easy install. Call the cabin from the cell phone an hour or two before the expected arrival, turn the furnace on. Warm when we get there.
    MICHAEL -- nj, NJ   1/22/2011
    This has really helped us out. Calling the controller and having my hose warm when we arrive is the best.
    MICHAEL -- fitchburg, MA   1/13/2011
    1/13/2011 Sorry about the poor rating I have had this controller for many years and have been very, very happy with it. However 4 years ago I switched to comcast from AT&T telephone service and the unit will not work with comcast. I was lucky and had a AT&T business line extension in my house and switched the X 10 to that line and it work well. Again I was very happy until a month ago, The unit produced a hi pitch when I called into it. It did not work! No problem, I was happy with the product so I just re-ordered another X 10. Much to my surprise and dismay I go the same hi pitch when I called into the X 10. It seems AT& T has installed fiber-optic cable on our street, I do not have the fiber optic service, but my X 10 does not work any longer either, I am very disappointed that I have loss the use of my X 10 it was a great product while it lasted for me. I called the company directly about it but they denied having any problems with it. Now I have the two perfectly good X 10's that I cannot use. Thanks for asking Mike
    CONSTANCE -- new paltz, NY   1/4/2011
    I haven't actually used it yet, but it was easy to understand and install. It seems well made and reasonably priced.
    GREG -- bloomfield hills, MI   12/30/2010
    When it works - it can't be beat. Over the past four years, this is my third controller. The first stopped working and as it was still under warranty, was replaced at absolutely no cost. The second worked for two years and again stopped - warranty was measured relative to the first device and so had to buy the third one at full price. Arriving home to a warm house, however, is worth what I'm calling the annual subscription rate.
    ROBERT -- rochester, MI   12/12/2010
    with your help, we now have a device that is very, very, good for our remote use. Once we learned to use this equipment, we became very enthusiastic and hope to add other products such as a warning device for low temperature in winter months.
    PIERCE -- oxford, MI   11/16/2010
    It's a great product, but does seem vulnerable to power surges or something. This is our third in 6 yrs.
    Mike -- Massachusetts   3/24/2010
    X 10 controller works fine, I have had mine for almost 8 years not a problem. I agree, not the prettiest looking thing. Unless technology has changed mine does not work with the telephone lines from cable company, I needed to use Verizon or AT and T. for the man with the set back thermostat. All you need is another thermostat 20 bucks, set it at 70 degrees, wired in paralleled with the set back stat and let the X 10 switch between the stats when you call into it. I raise and lower my heat from 50 to 70 all the time using two stats.
    GARRETT -- copake, NY   10/19/2009
    Great concept and it works quite well. Can't figure out why I keep having to replace it every year, though. Mysteriously stops working, but Smart Home has made the returns easy.
    CHARLES -- rydal, PA   10/12/2009
    Both units arrived quickly and are installed. They are working well as anticipated to provide a phone operated thermostat switch.
    John -- Parsippany NJ   4/11/2009
    It did not work for me - per the rep from Aube, it may be too far to a phone company component. To add insult to injury Smarthome would not refund my money.
    Don -- livermore, CA   2/28/2009
    Super easy to install, super easy to program, very reliable, can't get much better than this. We installed two in our house 6 years ago, no problems in all that time. We can turn it on and off in the dark with the simple manual 3 button controls. Looks good on the wall and we don't need glasses to read the display. We would recommend to anyone.
    JAMES -- york, PA   12/10/2008
    Works great! I hooked it up to my existing thermostat with no issues.
    WILLIAM G -- windsor, CT   11/23/2008
    Simple but works well. Hiding the telephone and thermostat connections in the case would have been nice.
    CHARLES -- foster city, CA   11/6/2008
    Easy to install. Good instructions. Excellent customer support from both Aube and Smarthome.
    CAROL -- covina, CA   5/19/2008
    So far, this unit seems to work as advertised and is exactly what we were looking for.
    BRIAN -- maple grove, MN   4/27/2008
    This is the third unit purchased as the first two did not work. This control has a loose part (rattles) in the unit. I installed today and it works fine.
