Only vape products I trust Only vape products I trust. Fast shipping and good customer service. My Flip Ultra has been with me for years and the all glass vape cartridges are by far the best on the market.

Don't waste your time or money Purchased a few of these for a family member a little over a year ago. They had a sale, so I picked up 4 of them at one time. They used two of them for about 9 months or so until the first one failed. After that they opened a new one still in plastic and it was DOA. Thought nothing of it and moved to the last unit and that one did work. Threw the DOA unit in the drawer to deal with later. Fast forward a few months now that the other two units stopped working, I emailed the company and received a response from their "customer service" I use that term loosely because they are REALLY bad at customer service. So, for those still reading this. We now have 3 dead units, and one was never even used. Customer service said that we would need to send the units in and pay 15 dollars each to have them RMAed. I did this with two of the three units. They received the faulty units and promptly cashed my check. When the two RMA units arrived, one worked and the other didn't. Customer service asked me to send a video of the non-working RMA unit and the DOA unit from the previous order.... almost like they didn't believe me. Once they had the videos of the units not powering on they sent me an RMA for the new RMA and a label and packing to return the DOA unit and the faulty RMA unit. A little over two weeks go by and I reached out several times. I was told this morning I would need to now pay another 15-dollar fee for another RMA for a unit that never worked out of the box. This to me seems a bit ridiculous because they clearly have a known quality control issue. Why have me send the unit back and not RMA it? Assuming they plan on refurbishing it and selling it as a new unit all while keeping the money I paid for it. This to me is unethical and I will not be supporting this company in the future. The product itself isn't bad but the issues and customer service make this a 0-star experience for me.

Great battery Great battery! Love that it is adjustable. Charges quickly and stay charged for a long time. No issues with the battery thus far. Would highly recommend:}

Thank you for the awesome vape Thank you for the awesome vape. Nothing better than supporting a fellow veteran business as well. Thanks

Trustworthy source for high quality vape hardware. Very pleased with the quality of product this company produces. You can just tell the product people are quite deliberate about the engineering and aesthetic choices that go into the production and sale of their hardware. There are so many companies producing this kind of hardware that DO NOT care about the quality or safety of their products - I purchased from several of them before I found O2 - and there is a world of difference here. Some examples of why I think they make GOOD STUFF: - Tasty carts. Everything I vape through their cartridges (both full-ceramic and non) tastes like... the thing I'm vaping through it, and nothing else! No metallic taste, no "dry hit" taste. Of course this depends on the thing vaped through it, and O2 can't control that, but what they can control for, they do. - Reusable carts. You get what you pay for. I have refilled my O2 carts several times before they start to get "stale." I have experience re-using carts from other brands like Delta Ape, and CBD is Better. No knock on those folks, they make fine disposables, IMO. But this product is superior for the environment relative to those, and in the long run, is actually cheaper per use, because you get more uses out of it. Of course this also depends on your usage habits and what you vape through them, so YMMV. - Well constructed carts. You can just tell by looking at and touching the carts that they are well-constructed. The silicon seals are of good quality. The glass is ground so as not to have any sharp edges. The carb on the airflow-adjustable carts actually works well. All of these things indicate attention to detail, and good design to me. - Stylish, discreet, and reliable, variable voltage batteries (I got two Nano's and two Lil' Bitty's). The "user interface" on these is as simple as it needs to be, and no simpler. They're efficient, no-nonsense devices compatible with a wide range of carts. AND, they're serviceable (of course you need to know what you're doing regarding circuits and batteries).
