Bests & Worsts Reviews from Amazon

If you vape and are trying to keep from annoying others, or would like to vape in public spaces such as the movie theater, a restaurant, or even a plane, this is the gadget you need. Take a big hit, blow through this, and like magic - NOTHING comes out the other side. My only gripe is that they don't last more than a few months... the filter gets full and then you can't blow freely through them anymore. This would be fine if you could open it up and clean or replace the inner filter, but there's no way to get in there. So you have to dump it and buy a new one. It's just not green/good for the environment. Hint hint - if the maker is reading this... make us a version that opens and charge us for the filter replacements... or just charge a bit more for the unit and make a washable filter... be good to the world.
