If you like small form factor devices and aren’t a high wattage vaper then the Smoktech Groove 2 might be what you’re looking for. This device will adjust from 3 to 6 volts or 3 to 15 watts. The best thing about the Groove 2, in my opinion, has got to be the 3800mah battery. This thing is gonna last a long time on one charge and that is a definite plus to me.

The Smoktech Groove 2 is a curvy device that is sure to be comfortable to hold. With an easy to read display and a super long lasting battery, many of you are going to love this device.
