    This device is way too large to fit in a standard elec. box. There is no way it will fit along with other devices. Probably should be a warning in your product description.
    BRETT -- windsor, CO   9/15/2011
    This thing works really well, but it is *huge*, and quite difficult to install because of its size, and because the lead wires are far too short, given its size.
    Bob -- phoenix, AZ   5/21/2011
    Worked! Arrived in a few days and working for my 240V USA pool motor. I have two 240 motors: one for filter and one for in-floor cleaner and luckily only needed to filter one of them. Note: be sure to look at the schematic, you need 2 of these for a 240V circuit. I bought two thinking I could use one for each motor, but had to put both on one. I will purchase two more to isolate the other motor just to be safe.

    I have used these to block noise from electronic ballasts which were interfering with the X-10 signals. It is inexpensive and does what it's supposed to do, but installation locations are limited to where you can fit a proper box (It is too large to fit in a typical light fixture). I have used both a metal three-gang switch box with custom-made blank plate, and a 60A A/C disconnect box with the guts removed.
    CHRISTOPHER -- campbell river, BC   4/30/2011
    Installed two on a 240V fluorescent light circuit. X10 wouldn't work on any other circuit while the lights were on before installation, works well after. The boxes are very large though, so finding somewhere to put them is tricky.
    STAN -- napoleon, OH   4/17/2011
    Purchased one and installed on UPS - Smarthome review suggested UPS is a source of X10 interference. Don't know if effective in eleminating interference, however, between this device and AF120's on Flat Screen Tv'S - x10 WORKS PERFECT!
    DONALD -- sun city cente, FL   3/21/2011
    Not yet connected. Hard to choose which line to put it on,. Rating of order handling and delivery. excellent.
    WILLIAM -- suffolk, VA   3/21/2011
    Did a good job removing noise from fluorescent lights and a generator battery charger.
    TREY -- ooltewah, TN   3/10/2011
    Working great. Used in my electric panel to isolated my new TED 5000
    WM -- great falls, VA   1/13/2011
    Only fixed part of the problem. Still have two X10 units that will not function when the interfering device is on. Two others that used to not function now work.
    Brooks -- baltimore, Maryland   11/26/2010
    Didn't realize this thing was so big, but that aside it did fix my problem of many CFL fixtures one one circuit Outdoor Floodlights causing the insteon switch to not turn off, only on.
    JASON -- fort lauderdale, FL   11/8/2010
    Works great. I used this in the non-conventional way that the TED5000 power monitor website suggests. Used it to block noise from entering the only circuit using x10.
    JOHN -- montgomery, TX   8/12/2010
    Arrived on time. Solved my problem. Very good value.
    DAVID -- salt lake city, UT   8/7/2010
    I installed this on a new dishwasher that has a dc synchronous permanent magnet motor and other high tech stuff. It helped some. A ccouple of light switches started working more reliably after I installed it. I have another one on the air handler of the air conditioner. The diswasher used to make a compact fluorecent lamp in the living room buzz during certain parts of its cycle.
    PAUL -- moreno valley, CA   6/16/2010
    Did not filter the power line interference from a battery charger that was giving me trouble.
    ROBERT -- star prairie, WI   2/13/2010
    It showed up when promised and worked like it was supposed to.
    DAVE -- brantford, ON   2/13/2008
    Very happy with your prompt and correct recomendation.Unit s easy to install directly into my furnace and has performed the expected "miracle" of no more disco lights! Furthermore, your x-10 competition did not even respond to multiple e-mails, so good on you folks. I am now assessing my needs to consider revamping my home controls to the Insteon platform but I'll need to read more and develop a budget/game plan. Thanx again, Dave K.
    BERNARDINO -- quebec city, QC   11/12/2007
    It is not a Canadian certified (no CSA ou CUL) product!
    DAVID -- bartlett, IL   2/18/2007
    Since these filters are hard-wired, it would be nice if the case would fit into a standard 1900 electrical (4x4) box. I removed the filters from the plastic case and installed them in a 4x4 electrical box. As far as filtering, they work great. The reliability of my X-10 system has been greatly enhanced since installing these on my fluorescent lighting circuits.
    JONATHAN -- buffalo grove, IL   1/10/2007
    It works! The main item missing from the Details & Specifications is the dimensions. Here are the dimensions for the next buyer: 4-5/8"H X 3-1/8"W X 1-5/8 D (dim are +/- 1/8"). This filter got rid of the electrical noise from the blower motor of a high-efficiency Trane furnace.
