Taugt or not right? What bringenh these parts?

I had been offered such Filterhülsen randomly and have simply tried impartially times.
I must say I was pleasantly surprised! Even so positive that I grew myself equal to a stock.
While it's a conversion to take the plastic sleeves and mouth, but the "smoking experience" is almost identical as without this sleeve. But you can see right away what to filter out these filters to nicotine and tar! This is crazy.
Result with me: My smoker's cough is decayed from one day to the other and actually gone !! I almost believed not, because I was rather surprised by this unannounced positive effect.
Unfortunately, I realized that next time I'm three or four cigarettes "without" this filter sleeve smoke, I just get my cough again ...
Better would be all quit smoking ....
Conclusion: Highly Recommended !!
