Awesome product and an unbeatable price!
I've bought this product multiple times, it's definitely a staple part of the kit if you're  travelling or in a car. Gets rid of all exhaled smoke visually and covers up the smell pretty well. However, be aware that if you're burning something there is always going to be at least some smoke in the air. It's not 100% effective  for this reason, but other than that, I love it!
