These plugs are more trouble than they are worth. When we first got them (4 total) they worked great. But after only 2 months, they are constantly "falling off" the network and have to be rebooted and added back on which makes them useless, especially if the plan is to have them as security devices to turn specific lights on/off while away. If they do drop off the network, you cannot remotely add them back on, they must either be reset with the physical button or unplugged to work again.
