This dimmer really did the job for me.
I purchased an old lamp at an antique store, but there were two problems with the lamp: the switch is rather hard to reach, and I don't absolutely trust the wiring... I don't want to leave it plugged in when I'm not around.
This dimmer switch was a great solution to both issues. The lamp plugs right into it. There is a long cord for the dimmer switch, so I can move the switch where I want it while leaving the light stationary. The sliding mechanism on the switch slides smoothly through the dimming cycle, but changes the friction level when it reaches the "off" position, so I know for sure when the power to the lamp is all the way off. Perfect. I can leave my lamp plugged into the switch with no worries about the old wiring.
Two other reviews struck me as a bit off, so I wanted to mention my opinion on each matter raised.
* One reviewer said that the switch has a little light, so she can find it visually when searching for it in her bed linens. The switch I received has no such light. This is actually better for me. Less power consumption, and I'm not one to misplace my switches.
* One reviewer said that you couldn't dim a lamp plugged into the switch all the way down, but that it would go half-bright or more. This is true when turning the switch on: it jumps from full-off to half-bright. But then you can dim it back down to where the lamp is barely glowing.
One other plus to mention: the switch works silently. No loud snaps when you're turning it on or off.
Hope this info has helped.
