Wish I had come across these 4 weeks ago. Bought a similar product from B&Q for £10, twin pack but remote only controls up to 3 sockets whereas this one can control up to 4 and also has handy feature of controlling all sockets at once. I use them for bedside lamps which has proven handy. My ones handle a maximum capacity of 1000w per socket however I could not see from the packaging on these what the maximum load was. Found in B&M Leytonstone.
