    Great Vape Pen. I have tried Dr. Dabber Ghost and Kandy Pen, and O2Vape is THE BEST I have tried so far! On top of that the O2Vape pen is half of the cost of those other pens. Would DEFINITELY buy it again

    Works great for me at all voltage settings.
    Lasts a long time between charges (3+ carts).
    Very satisfied.

    Outstanding battery. Charges quickly and it keeps the charge for a very long time. It feels sturdy without being super bulky. I’ll be buying more!

    Had the 900mah battery for almost a week now. I’ve been through roughly 15 different brands and O2 vape seems to be the winner. Smart design and great idea with the light blinking a different color than temperatures for the variable voltage feature. Smooth button, clean hits, holds a solid charge, and 900mah! I will definitely recommend and be back.

      Thanks Jessica! VAPE ON!!!

    Excellent products and customer service! The 900 lasts several days between charging! O2 Vape guarantees their products

      Thank you Kari!

    This is an excellent battery indeed. Why anyone would give this battery less than 5 stars, considering it has a lifetime warranty, is beyond me. This price is on point and the only “catch” is I have to pay to ship it back if/when it goes bad. Excellent product! Thank you very much!!

      You are most welcome Luke! But THANK YOU !!

    This is now my 3rd battery from 02 , ive been using this brand for maybe a year and a half now and ive never had an issue. Ive given one battery away and my other 2 i use one for home and the other for work. They stay charged for a few days and also the connecting end never gets wore out like some of the competitor brands. I will always purchase from 02!

      Thanks Hayden!
