Great products & service!! I had problems with a pen I purchased along with not liking it at all. I called they were super friendly & helpful. Not only did they replace it but they exchanged it for another item I wanted!!

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:}

stopped working after 45 days. stopped working after 45 days. After reading other reviews, I will not be asking for an replacement, I've already thrown it in the trash. Just a waist of your hard earned dollars.

Their shipping costs are outrageous! Their products are okay. The vape batteries don't seem to last as long as other brands and the charger is terrible on the pen batteries. It stops charging after a while and I've had this happen on 3 batteries from O2Vape so it wasn't just one battery. My real problem with O2Vape is their outrageous shipping costs. You will double your total costs when you check out just due to their hidden costs in their outrageous shipping. Your shipping costs ARE HIDDEN. The buyer can't see the way overpriced shipping/handling fee until after they have given their credit card at the very end of the transaction. If I buy a vape pen for say, $40 there, the shipping and handling would be almost that much so yes, the price doubles with your outrageous shipping costs. What a way to rip people off.

Good service but the product was… Good service but the product was subpar. Of the the 2 batteries I bought one stopped functioning a month into light use and the second is on its last leg after heavy use in the same amount of time. The first one the battery says it’s charging but then won’t fire and the second needs to be held the correct way for function.
