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.

Very poor product Very poor product. Lasted maybe two months and would no longer work.

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.

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!!!
