Unfortunately, they are very susceptible to interference.
Metal, whether on the wall or as a heating pipe in the vicinity are obviously bad for this receiver, even the supply line in the wall, if it runs directly behind the appliance, may cause harmful interference.
Can be used the receiver so only if directly behind or any major metallic objects or electrical lines carrying current to be laid next to the device.
The best plug at the end of a multiple socket and so put no second receiver closer than 50 cm, because the interfering also with each other.
Well, okay, I know the problem yet of old VHF radios which is interfered directly next to each other under certain circumstances, but in these receivers, the antenna can not change from the position if then only with the entire connector housing, because they fixed (rigid) are installed.
So who keeps this wireless control receiver Remote only sporadically and with enough distance to his fellows and other electromagnetic or non-magnetic metal objects certainly has his fun with it, but who wants to attach more than one recipient at one point, is certainly better with combination devices for the box installation canceled because since then three units can be controlled with only one receiver built outlets and also the recipient is still in the flush-mounted socket rotatable, so that, although is just an optimal alignment of the antenna in one plane only, but at least, possible ,
Otherwise, a good product and certainly a fun gimmick, if you eliminate all confounding factors.
