This product performed as expected. THere is definitely a "sterno" smell. It is not overwhelming but we decided that it was too much for regular use. We now only use the gel in the "fireplace" when we have an event such as a holiday or family gathering. We open the windows so the smell goes out. It's a waste of energy but only for a little while. If the house is full of guests, opening the window , lowering the thermostat and using the "fireplace" make for a pleasant effect. When this runs out I will try a different brand to see if there is less smell. If not, I'd probably buy this brand again. BE SURE TO REMOVE THE LABELS when you use it. Not doing so definitely contributes to a toxic odor.
