I recently purchased this and it works perfectly, but it was too large for my needs, so I'm going to replace it with a smaller size. It's practically new, having been used only twice. The food odors are gone. d(^_^o) Just in case, I'll keep Dr. DEO in it and continue to ventilate until it's sold. It's sure to be a great help in the coming season! Please use it when camping or going out. Thank you for your consideration.
