“O2VAPE was successful at creating a vape that excels in functionality and aesthetics. Everything about the design actually serves a purpose, it’s not just trying to be fancy to show off.”

“This is one of the most unique vapes we have ever encountered.”

-Ganjily.com

“When a simple, high-performing vape device comes across our desks, we usually give it top marks. And the O2VAPE Flip Ultra might just sit atop the growing pile of options out there. One of our test oils — a pure, blueberry-tinged blend — absolutely sang using the stock combination, right out of the box.”

    I’m new to smoking and decided to add carts to my routine. I came across this battery after searching all over and I IMMEDEATELY decided I wanted this one. I can’t see why anyone would buy any other battery – it’s perfect. I have ZERO complaints. And from a company run by a fellow veteran?…can’t beat that. I’ve had mine about a year now and I love it.

    I stopped smoking carts for a few months. I went back to it. I pulled this baby out of the drawer after all that time. It had 4 bars of battery still! What kind of magic is this? It’s also a very cool looking & quality vape experience. Had to swing in real quick to leave this review because I was very surprised how this holds up.

    I love it. I have used it daily since January and not had one issue. It charges fast and having option of charging ports is awesome along with passive charging they literally thought of everything. I do notice it gets hot when charging that is my only concern but considering it has a lifetime warranty not to worried.

    I bought one for myself and a friend, we both think it’s awesome. We get carried away with the flip n hope it doesn’t mess up over time… haha my wife hid my battery in a 1/4 inch of water by accident, she didn’t know about the water haha.. but I found it and it still works perfectly. Me and the wife thinks it’ll be better with a drawn down conceived action to hide it vape completely to look like a actual car key fob
