The Silo by CCell is a tiny, ultra-portable but powerful concentrate vaporizer that delivers a hard to beat experience. The Silo is incredibly easy to use with no buttons or adjustments to make, just attach almost any 510 threaded oil cartridge to the included magnetic adapter, insert and inhale! An LED will illuminate while the heater is activated, and you only need to inhale for 2-4 seconds at a time to produce a surprisingly large and super smooth draw. The Silo is incredibly small and portable, just look at the size compared to a standard Bic Lighter! A full cartridge and battery can last for many, many draws - up to a week of use or more for many users!
