Best smoking accessory ever!
Best: works 100%<br />Worst: disposable<br /><br />While this product will not stand up to daily use indefinately, it will survive a few months with two people sharing the unit daily.  I give this product 5 stars.  I also have the SB Jr., and it lasts a couple of weeks tops.  It serves it's purpose, but this unit is better for the home or commutes while the Jr. version is better for pocket carry use.
Rating: 5 stars
