New homemade wax warmer

There are 2 seemingly never-ending questions:
1) Can I use a microwave to warm wax? A: Some find it acceptable, others not.

2) What's the best way to warm wax? A Nearly anyway that provides consistant 115f heat... microwaves tend to be worst performers here... they really don't provide a heat source as they scramble molecules to create heat)

And so I set out to design what I thought is best:
1) Something that can be done fairly inexpensively ( around $60).
2) Something that can be done with off-the-shelf items
3) Something that safe ( but you get the standard disclaimer ... you are responsible for your safety... I made no claims here! )
4) A device that heats top and bottom.
5) A fully adjustable device.

I think this meets all those requirements.

Here's a video for more details:
