Amazing hunt @direwolf,

Here in Brazil I think we don't need the product, however people who live in places colder, that is an amazing product.

Pros:

Help people who live in cold places warm their homes without any fossel fuel solutions.
It's eco-friendly and, as I see it, easy to install and good for small places.

Cons:

I did't see the price of that, but maybe will be a little expensive.
