I really like the vapor bros. it is less then half the price of the valcano and works great... i tried the bc style vaporizer (my friends) and it made the weed taste like plastic... so after one hit on that we turned on the vapor bros... and tasted only the fresh sweet taste we love... no smoke only vapor unless you have the heat to high... also i no longer have the cough that had developed from smoking... still enjoy a joint/blunt once in awhile tho.
