Perfect for pool pump
This is perfect for an above ground pool pump. I can turn it on in the morning from inside of the house.

ease of use
great product, used basically for Outdoor Christmas decoration. I have a Phillips outdoor outlet switch but has a light sensor so basically turns on and off automatically, but this one works fine with 3 switches

Works great for patio lights
We used to have out patio lights on timers, but switched to this remote control so the lights weren’t on when we didn’t need them. Now we keep the remote by the door and easily switch the lights on when we are using the patio or taking out the dogs. Very happy with how it works.

Great for remote switching of loads. Installation is truly simply. Purchasers need to be aware that to be weatherproof, both receptacles of the switching unit need to protected from ingress of water, even if only one load receptacle is in use.My repeat purchase. First unit was used last winter, to switch roof de-icing cable. Worked perfectly.Would recommend this product.
