I had a hard time deciding what to rate each option , 3, or 4 or 5 stars etc. I can't compare this product to any other brands, as I think this is the only one. Also, I am not sure if this is a suitable product to review, but as a cigarette smoker, I was glad I found these little gems.

They reduce 90% of the tar in each cigarette and reduces stains on teeth.
One filter is good for 5 cigarettes.
After 2 weeks of using this filter I have got rid of the "morning cough".
The cigarette is way smoother to inhale as well, and reduces the amount of actual Nicotine you inhale, so gradually you smoke less and less as you won't crave or "nic out" as much.

I was given these from a friend for a New Years Gift. I have reduced my smokes per day, and hope with this initiative, I will quit soon.
