Works great, but there is a bit of technique to it
Works great!  It really gets rid of the smoke odor that you blow out through your respiratory system.  However, you still need to address the smoke that comes from your smoking device.  There is a rhythm to this.  First, take a deep hit from your tobacco of choice and - while still hitting it - cap the open end.  Hold the smoke, then blow it through the smoke buddy while you're still capping the end of the tobacco smoker.  Once you've done that, take another hit from your tobacco pipe to clean out any residual smoke, then blow that through the smoke buddy.
