The Sai Plus, the Big Brother of the Sai TAF, is a Larger Atomizer for Larger than Life Loads!The Sai Plus wax attachment is built from heavy duty metal for maximum durability and a premium look and feel. It features the same top/bottom adjustable airflow design as the TAF, for full airflow control. The top section has an integrated splash guard to protect against oil splatter and the mouthpiece is fully removable. The Sai Plus is 510 threaded for compatibility with nearly every sub-ohm box mod. The Sai Plus is compatible with several optional styles of heating coils; each heating coil has different strengths and all perform differently to suit all styles of fully melting concentrate. They are easily removed and replaced for cleaning or swapping coils. One Titanium Bucket Coil with an embedded ceramic heater is included with the Sai Plus so all you need is a 510 threaded box mod (with enough room for this big boy to fit on top) and some oil to bring the clouds.
