    I’ve been using o2vape products for the last 3 years, and this one certainly doesn’t disappoint! I love the fact that it allows you to change the voltage, and it’s extremely sleek and discreet. Will be a lifelong customer.

    Bought two of these. Black and the Silver version. Been using them both for a few weeks and they work great. The variable temperatures seem to be working as intended and it helps that they’re really sleek looking batteries. I like the unconventional “dial” to change the temperature and was uneasy about changing the temperature this way but haven’t had an issue so far! Their customer service is also great. Called them when I thought USPS had messed up my order by giving wrong tracking info but my package got to me the next day. Hate USPS’ unreliability but love the batteries so far 🙂

    Awesome product. Definitely a quality piece that delivers great results. Only bought one to see how I like it, but will definitely be purchasing more. Well worth the extra few dollars you’ll spend versus one of the cheap knockoffs

    I have been frustrated with other pens, lack of battery life per charge, uneven heating etc. Bought the O2 vape pen and have been very happy with it. The adjustable voltage seems to give you a bigger jumping off point if you like. Very happy so far, have tossed all my other pens. This is a winner at a reasonable price.

    I have had mine for three days now and love it. I like bumping up the temp sometimes so that’s very handy. Thanks, DH

    O2 Vape VARI VAPE vs CCELL palm? I’ve had my O2VAPE for about 1 month now it still performs excellent!! Well I let my curiosity get the best of me and bought the damn palm battery. Was talked into getting the battery seeing as I use CCELL cartridges and that combined would make it all taste better and last longer! That’s what got me! Will the oil LAST LONGER! Holy shit! It definitely DID NOT LAST longer at all!! It is cool and convenient and no button and descent battery life of around 350mAh? Anyways, the new CCELL palm battery has already stopped working after 2 days?!! RUBBISH! Plus it so sucks through my thick ass pure distillate I fill my carts with! Also for some reason which ppl will say I was hitting it too hard but I wasn’t seeing as I love the fact of not having to heat it long and still get a descent puff. Remember it’s 92.2%. So a couple puffs and ur good! O2VAPE still working GREAT and very reliable w/ no issues at all and it does do it’s job of conserving your oil unlike the supposed new tech of a CCELL battery working best w/ CCELL cartridges. I can’t find a reliable answer for this question. The palm rubs at 3-7volts! No wonder you get big clouds!! So as long as 3.3 volts works for my distillate, it’s the obvious choice and DEFINITELY BETTER AT CONSERVING AND MAKING YOUR OIL LAST AS LONG AS YOU WOULD WANT IT TOO!! AWESOME PRODUCT!! I wish I had more of your batteries to review!. Vape on peeps

    I bought this earlier in the week and it arrived yesterday via the mail man. It is awesome and I'm really digging the variable voltage. Get one!

    SO pleased with this pen!! The shipping was very fast and it came with discreet packaging- which was unexpected but I appreciated it. It arrived charged as well. I’ve been using it for about a week and I’m really impressed with both the battery capacity and the voltage dial. I ordered the rose gold color which is surprisingly gorgeous too. Highly recommended!!

    I got one of these a few months ago- silver for me, and rose gold for the wife. These little bad boys are great, for the first time in my life I actually wanted something that was rose gold. Don’t let the name fool you! Yes it is rose gold, but the color is somewhere between bronze and rose gold. Don’t tell the wife, but I think I look better holding it than she does. I ended up giving the silver one to a buddy and now I’m here wondering which one to get: woody or rose gold. The matte black with its soft texture also feels great. Decisions, decisions. While buttonless are nice, O2Vs vari-vapes are my favorite battery, hands down.

    Just got my battery on Saturday and I absolutely LOVE it! The shipping was extremely fast and so far it has exceeded my expectations in design and function. I used to like my Old Spinner 2 battery but it was a bit bulky and would break easily. Now that I have found these products as long as the quality is consistent I will be a O2 vape customer for life!
