I use this in my car, just because I'm scared the only time I'll get pulled over will be from throwing my cig butt out the window. I like this a lot, the light makes it easier to find at night, and the cup holds a lot. It also does a good job of keeping out the smell. To put out my cig, I just swirl it around on the metal a few times then drop it in the hole and close the cup.

The light looks good, but the product is made from cheap material, nothing special. My recomendation, do not smoke in closed environements, stay outside or quit. I have chosen to stay outside.
