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.

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.

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.

Tried to re-order a product which is impossible to do Tried to re-order a product. Opened their website 3 times. There is no search function on the O2VAPE website. Called customer service to order and the person who answered said she was new and not at her desk, put me on hold for along time. I finally asked to speak to a manager. The rep cut off the call. A manager called back. He was was extremely rude, blaming my computer and me. I don't know how this company stays in business. I noticed that 25% of their customer reviews are "1 star". I will now buy my products somewhere else!!!
