Its not perfect, you cant smoke a joint or pipe inside and expect it to not smell at all.  The smoke rising from the joint or pipe wont be caught.  You CAN pack yourself a one hitter and if you clear it, you wont have any smoke from that and you'll be able to blow it all through the Smoke Buddy.  Tip: there is a little area between where you put your lips and the start of the filter.  When you take your mouth off, it will be released into the air and not through the filter.  If you remember this, breathe out through the Smoke Buddy, breathe in through your nose, and then out again through your Smoke Buddy and all of the smoke inside will go through.
