Holds a charge for days, lets you change the amount of power your using as needed. Easy to charge and small enough for a pocket.
I have been ordering from these guys for a long time. Speedy delivery and good quality!
Shipped quick, it took a couple tries to get cartridge to sit right, collar holds cartridge nice and snug, adjustable power, light up screen, compact, the cartridge height adjustment is easily moved-so I just keep the cartridge sitting all the way down into Yocan unit, which is fine. Nice big square button to press, nice positive "click". Overall very happy with the purchase, maybe more metal instead of plastic would make the tactile sense more pleasing, but durability doesn't seem to be an issue. It is also a bit bulkier than some in the same design class, but only slightly more so, but I like the enhanced angles, makes it nice to hold. Very consistent smoke, I would purchase again.
