    This vape looks hella nice with the glass cartridges they sell on this site and feels really high quality when you hold and use it. I really like being able to adjust the temperature especially making my own oils with varying consistencies.

    Great pen, slim design and works very efficiently, the higher volts are for thicker oils and / or metal coils as they will burn out a wick; no complaints.

      Thanks Jonathon so glad you are enjoying it !

    Awesome pen battery! The variable voltage control is well built and easy to use. I live on this battery with the O2 glass ceramic refillable cart, only having to recharge every other day. Feels great, looks great, works awesome! What’s not to love?

    Wow! Love this pen! I had a button battery before that I didn’t care for but this beauty is easy to use and powerful. I like sharing this pen with my husband because he likes a less potent draw so I turn it down. Very smooth! Will get more as gifts.

    This is the best vape pen I have ever owned. Not only does it look really nice but it actually works! My old pen barely gave me any vapor at all and I thought this was normal but even on the lower setting ( and love that it is adjustable) , this is more potent! Service and ordering was easy and fast. I will be a returning customer. !!!!

      Thanks LJ so glad you like it 🙂

    Shipped quickly and has been working great in the first week of use. Stylish, effective and affordable don’t usually happen at the same time but O2vape got it right

    LOVE LOVE LOVE this pen! What used to take 6-8 hits now takes 1 thanks to the variable voltage. On top of that it’s thin and looks amazing with the chrome/glass cartridges. Great Quality! I recommend them to everyone!

      Thanks Fernando ! Glad you love it !
