Does just what it promises - turns on the power for 1, 2, 4, or 8 hours, or endlessly at the push or two of the one button!
Exactly what I wanted, at a moderate price. It covers more space on the outlet than I'd like; if placed in the lower plug on a dual outlet, it blocks the top plug, not a fatal problem.
11-18-09 I bought a second, to run more electrical appliances for specific numbers of hours and no more.
4-2-10 The one I use daily for an hour finally blew some interior component, so I got another. A very handy device.
1-15-11 Still using daily to turn on a space heater for a hour to either pre-heat the cold bathroom for use or dry it out after showers. Invaluable.
3-15-11 The replacement blew out, but I had another as a spare to swap in. Maybe running a 1500 watt heater an hour or two a day shortens the life somewhat.
