Great for cleaning small clock parts and gears. It's onboard heater is a plus I have used this a half a dozen times so far with only one issue. When you use the heater function it doesn't turn itself off once the preset temp is reached, just need to keep an eye on it so it doesn't over heat. Some other users have commented about letting the magic smoke out of the heating element, I think the secret to keeping the smoke in is to add water close to your desired temp and allow the heating element to come up to temp before you turn the unit on.
