I bought 4 plugs with their 4 corresponding remote controls since they have 4 independent channels. Reliable, effective. They did not interfere with other remote controls I have. In case of a power outage, they stop, but they do not lose the channel you have tuned them to. Coverage of the whole house and from floor to floor. They can handle a large load like radiators, large heaters..). Caution is needed if you tune one plug, for example, to channel A and then decide to tune it to channel B. The plug will remember both channels. If you do not want this, you must press the tuning button for 4-6 seconds and stop the other channel. After a few months, I bought another 4 identical plugs. None of the 8 now interfere with each other (unless you want them to). However, two plugs that I had connected consecutively to the same 2700 W quartz heater broke. (Their relay does not sound while the remote control light blinks normally. As long as it works with the 2 quartz bulbs, i.e., 1800 W, everything is fine. If I turn on the third bulb, sooner or later it will burn it out.. and the plug will get hot.. Conclusion: With quartz heaters, be careful even if it says for more W. Obviously, it passes more current. Also, you cannot unscrew it for repair! They have put screws that only screw in!! This, of course, is for beginners.. And in a way, they are doing the right thing. Now I will buy another four!!
