    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.

    This was a gift and its great. I was told that this has a real life time warranty. I’m very impressed with the function and design, we shall see about life and warranty but I am hopeful its as impressive as the design and function.

    Fantastic Design ..pair it with the O2 vape cartridge with variable vent system ..and its a serious little evryday carry system for using with high quality thick oils

    Great battery, small discreet design.
    The pre-heat feature is nice and often overlooked, along with variable voltages.
    Performance and reserve capacity are great as expected.
    Only thing I can say that is not mentioned in the instructions or on the website is the LED changes from red to blue when done charging (was wondering during first charge before use).

    Fantastic unit! The things I love about it are: 1) It’s tiny. 2) It holds your cartridge upright when you’re not using it. 3) You can charge it with a standard USB charger. 4) It’s feature-full with pre-heat and variable voltage. 5) Did I mention that it’s tiny? It’s my new goto portable vape. I just bought another one for the wife.

    To steal a line from Dr. No “hits like a brick through a plate glass window” compact and lethal. Tried all levels…first is perfect for me…second is wow…third is good night.

    I absolutely love the Nano! It’s perfect. Super small and still rips. The battery life is surprisingly long for the size, I easily go 2 – 3 days without charging. The only warning I can offer is to be sure to turn it off before you put it in your pocket or purse, it will run…you won’t know…it won’t end well. Seriously, you cannot go wrong getting one of Nano of the FLip Platinum.

      Thank you Heather So glad you love them ! Yes, we recommend turning it off before storing in a pocket or purse as stated in the instructions and on the website! Thanks again, enjoy!

    Damn. Tiny vape packs a big punch! Just received mine and it’s got all the features of the more expensive vapes! Haven’t tested the battery life yet—will circle back and report.

    My wife and I absolutely love this product, and have used it every day since. I’m looking forward to ordering more products in the future, and also sharing with friends and family how great these products are. We are in the process of opening up a new tattoo studio here soon and looking forward to having these products in our studio!

    Keep up the great work, the quality is amazing and the product is amazing. Fast shipping, and I’m sure the owners are just that is amazing!

    Surprisingly powerful. It sports a nice heft for such a tiny object. I wish the high temp setting was 4.3 rather than 4.0, as in the Platinum Flip pen. This is a well-made product.

    My review is short but direct…I have nothing to say but ‘good things’ regarding my O2 Vape purchases! After 45 years of buying products like this, O2 Vape has hit a home run with me! Why? just ask Phil
