With many "Conserve" products, Belkin doesn't necessarily create a brand new concept with their creation, but they excel in design and execution!
I am a fan of their remote-switch "Conserve" power strip, and I love this little gadget too.
It's essentially just a timer for an outlet, not unlike the existing products you can find on Amazon, but Belkin greatly simplified the controls, and made it so the power timer is on-demand instead of on a schedule.
Unlike the relatively complicated dials of some other timers, the controls on the Belkin Conserve Socket are pretty much idiot proof. There's a switch on the site that lets you choose from one of three time increments (1/2 hour, 3 hours, 6 hours), then a button on top to start the timer. It then shuts itself off when the time elapses. That's it! Easy.
It's perfect for keeping a lamp on while the kids go to sleep, for charging gadgets where you want to reduce phantom draw, and this Christmas, I think I'm going to try it out for attaching my Christmas tree lights (turning the lights on only when we want to for a time).
Overall this is a nice, simple (and inexpensive!) product.
