Rokin / With three different temperature settings and a dual quartz rod atomizer to suit every dab-on-the-go situation, the Rokin Nitro Vaporizer hits like a champ. Not to mention its cool design, which although it resembles quite a few other concentrate vaporizers, has an overall element of sleekness and is made of quality materials. The Nitro pen’s chrome-like rose gold exterior is quite classy, giving it that “Ferrari of vaporizers” type of look and feel.
