    This little lady rocks your socks clean off. It stores and displays your carts in the upright position and does it with style. All functions work as advertised. The variable voltage makes a big difference and each setting provides a different level of cloud and hit, which I imagine helps with oils of different viscosity. I find the lowest setting provides nice hits and conserves oil slightly but the middle setting is just perfect for me. The hits taste and feel amazing. The last setting is great also if you feel like tearing your head off. Be aware that I don’t know if the picture does justice to how small this thing truly is, I’m worried i may lose it. It’s probably about 2/3rds the size of a lighter (adding in the tip of the cartridge).For people wanting discretion about their sessions this is perfect. When I’m hitting it, it looks like I’m picking some food from my l teeth or wiping my lips, if i want it to. No one will know what your doing as this tiny thing disappears in your palm, unless of course you exhale your vape cloud directly in their face. So After that long mouthful of a review , the only con I could come up with could be that the price may seem a little high to some people at $40, but it’s really not if your considering the lifetime warranty action and the fact that they try to fix it for you and rectify the situation if it stops working. Very happy with all o2VAPE products I’ve tried thus far( Vari Vape XL, Nano battery, Vari flow cartridges and Ceram-x wax pen, review on that pen coming soon)

    The form factor is what sold me on this device and the performance of it is making it my favorite vape I own. Everything works as advertised and all the different functions are totally adequate for the cartridges this uses. You really don’t know how small this thing is until you get it, and that is the awesome part about this little guy. For what you get for the price this is
    a great small form factor vape.

    Wow! It fits the Large bottom 510 cartridge, I’m impressed with how strong the hit is. Fits my larger Lion cartridge. Stoked!
