Needs some improvising

This product is not really made for wine making as claimed. Wine must have an air tight airlock. If you place the thermostat on the out side of the bottle you risk the temp going too high and causing hydrogen sulfide which causes a rotten egg smell. Because I wanted this item to work I improvised an airlock with a second hole to allow the thermostat to be inside. You can buy these on Amazon but need to work on it a little because the airlock needs a larger hole. Picture enclosed. Also, the rubber bands that came with this broke in a day, don’t trust them.
