    Had an initial problem, wouldn’t hold a charge, called Customer Service and talked with Seth who was excellent in helping me and had a new one sent out the same day and it works great. I can only praise the product, the company for honoring their warranty and Customer Service for being quick and efficient!!!|Accolades and superlatives!!!

    Beautiful pen. It works well and holds a charge for a long time. I wish I could control the temperature but other than that, I am pleased.

    • Dana E. Shoched

      Thanks Michael, We do sell variable voltage pens so next order get one and then you will have the feature you want 🙂

    I am a quadriplegic and without hand function, so an “auto-draw” battery is my only option. After years of using the smaller version, I decided to buy a couple of these for the longer battery life. These are powerful batteries and make each hit smooth and consistent. You also get fewer clogs than when using the cheap, made-in-China (no offense to the Chinese people) batteries. Using a lanyard, it’s always available, and I am in heaven. The faux wood finish looks nice, and they make excellent gifts. The friendly customer service and lifetime warranty aren’t bad either.

    The only thing I wish they had is an auto-draw battery of the same capacity but a lower fixed voltage. If O2 Vape had a buttonless 2.6v battery for vaping rosins, I would buy a couple more. My only criticism is that the shipping is steep; however, these batteries are top-notch. I recommend buying two and using them in the rotation because if the day comes that one does give you a problem, you’re going to need a backup, or it will feel as if something is missing in your life.

      Thank you Rob!

    Amazing product, such a easy smooth pull!

    I truly wanna give this 5 stars, but only reason it doesn’t, is because it only has one charging port. That sucks I will say, but other than that, I will quite say it is perfect. It puffs great, charges super fast, on normal use, I will could last almost a week. Over all, a great product for the money and even better when backed up with a warranty.

    • Dana E. Shoched

      Thanks if you want a pen that has 2 charging ports try our Flip Ultra

    Great products. Highly recommend. This is my second time purchasing O2vapes. I now have a back up one to use on the go and one for my sister.

    We have Three of the buttonless version, and all of them work great. We first got one in the woodgrain finish. It worked so well that when we decided to buy more (to keep various strain types in separate pens full time) we chose two more – the black one and one in silver. Draws great, holds a charge even after months of use, and they look good, too!

    Great product, nice price, quick delivery, service is wonderful. Hard to beat.
    Does seem postage is a bit high though. Still very satisfied.
