This was an estate sale find which thensat around my garage unused. It's time to pass it along to someone who will actually use it.

The grease warmer is a great idea for this area but I've never tested it. It doesn't look to me like the warmer sleeve was ever removed from the original packaging.

The batteries are old Ni-Cd (Nickel-Cadmium) and only hold a charge for a few minutes. When I looked the cheapest option was to buy an aftermarket battery for around $30.

This is being sold as is, in used but near new condition. Please feel free to message me with any questions. Thanks for looking!
