The product is smokeless but it is not odorless. I have a candle inside the house in a room of ~15 square meters and it gives off an annoying smell.

It does indeed appear smokeless.
However, as a material, before lighting it, it literally stinks everything it comes into contact with (hands and other materials) and its smell lingers, while the narrow mouth of the bottle easily splashes and wets everything with the slightest movement. :(
We will see..

Excellent, especially if you want to use it indoors because it is smokeless and does not smell at all!!!!!
