Note: Adding a small capacitor across the input is a good idea, do NOT add one across the output. This dimmer is not designed to drive fans, motors, inductive, or capacitive loads. Positive is common, negative is switched.

As a trial, I used a 12v battery for power.
When turned, the knob has a smooth feel and varies the lights without flickering.
It can be set from off to full brightness, and will dim to a very low light level without flickering.
I checked for RF interference with a Sony walkman, and there was no FM problem, but AM interference was heard within 2 ft of the dimmer, or a few inches from the strip. No problem at all 8 ft away.
The case is very sturdy, but a bit bulky.
I wish they made one with a long shaft to mount inside a cabinet with the knob outside the cabinet through a hole.
I took it apart, and it is possible to cut the wires and splice in a similar value potentiometer mounted through a cabinet wall.
Bottom line, I'm buying more of these.
*UPDATE* 1/26/12 -
After hooking up to a switching power supply with 2v ripple, there is a slight buzz mid range if loaded with 3 or more light strips, over 25 watts. Not very loud, just noticeable from 2 ft. in quiet room.
I purchased two more and found a difference in the circuit boards. The latest ones I received have smaller circuit boards and do not buzz at all. The newer model isn't as linear as the older one though, there is a jump in brightness near highest setting. Not very drastic, but there none the less.
I replaced the potentiometer (it's a 1k) with a longer shaft model, to fit through a 3/4" cabinet wall. The unit is inside the cabinet, and the knob outside. Looks much better.
Overall, I'm very pleased with both models.
Looking at the user-uploaded photos, it appears the circuit board design has shrunk over the years. The plastic box is now way bigger than the components require. The box measures 3.5" x 2.35" x 1.4" deep (if the pot knob is added, it's 2.03" deep) and can be mounted using #6 round head sheet metal screws.
Looking inside, though, the circuit board (in my unit) is only 2.21" (including the wiring block) x .987" x about .73" high (including the wiring block). The pot is attached to the box lid via a 3-wire jumper that attaches to the board via a small plug that is removable. (See the attached picture.) It would not be too difficult to make this thing smaller if desired or remote the pot to another location.
In my application dimming undercabinet LED strip lights, I hear no buzzing, the LEDs don't flicker and the dimmer smoothly dims the lights from zero to full, although the nature of LEDs is to "pop" on instead of smoothly ramping up from zero. They simply don't turn on until a certain amount of voltage is present.
I employed 4-conductor 18-ga wire to feed the 12 volts down from the power supply (which is on top of the cabinets) through a wall cabinet to the dimmer mounted under the cabinet, then back up to the main junction that feeds all the LED strips. The undermounted dimmer is convenient to locate by feel and adjust to the desired brightness quickly and reliably.
The beauty of these LED strips is that you can light five meters of length with only 24 watts at 12 volts, with almost no heat.

Opened it up and found the wire to the rheostat broken. Re-soldered it and it still didn't work.
