  1. Great for one tank of juice

    Posted by Too good to be true on 13th Dec 2012

    Orings too tight in the bottom, too loose in the top. Cap is almost impossible to remove or adjust. Very pretty, very clean, but damn. $80 for something that doesnt work and has no support with it...

    JJ said on the forums he was going to send replacement o-rings to everyone who had purchased one. This was back in May.... glad I didnt hold my breath.

  2. Beautiful, sparkling and clean

    Posted by Via, the Vocal Vaper on 30th Nov 2012

    This is one beautiful tank...pricy, perhaps, but it produces a great vape experience. It's as easy to use as a bella or JonBoy...and atop any of my batteries itis a thing of won't see every other Vaper in town with one..and everyone is sure to notice that you are using it...yes, treat it as you would every other glass tank you have, is comparable with a Phiniac as far as glass strength is concerned and has a nice hefty feel to it. I recommend wetting your carto down ith a drop of juice before inserting, to lubricate the o-rings for easy insertion!

  3. Incredibly delicate

    Posted by curt on 23rd Aug 2012

    I bought the duo and as already noted, it is very delicate. More like crystal than an annealed Pyrex. Mine lasted less than 24 hours. Lots of condensation in the mouth piece and it also doesn't seat well. I have other Pyrex tanks that are solid as a rock and thought this would be a nice addition to my vaping arsenal. Very disappointing, especially at $80, ouch. Tried to email J.J. twice and no response. May be out of business all ready. My recommendation to Avid is that you don't carry this product. It is a beautiful tank but not ready for prime time.

  4. So fresh and so clean,Clean!

    Posted by Bigmike on 24th Jul 2012

    I use a 510/801 adaptor with the 801 fusion cartos on a Provari. It's amazing!

  5. Great for a modicum of improvement

    Posted by sedge on 29th May 2012

    I got a parva and a duo. I like the parva a bit better. Both are amazing and make the juice taste great. They are build solid and the glass clarity is amazing. I just think the parva is easier to fill, plus I can use my Trippies on it. I do love the tip on the duo, but I find that the top cap can slide down too far sometimes when refilling if not very careful. I think the top cap should have a lip so as to alleviate this factor. A couple of suggestions: 1--for $70 you should include a replacement set of o-rings, and 2--give the option on the duo of purchasing both the ming and pawn tip.

  6. It looks great but....

    Posted by gene f on 28th May 2012

    Very delicate (it is glass after all) and the top cracked the second time I tried to fill it. Would definitely NOT recommend for every day use, there is simply too much fiddling involved. The O rings do not stay in place and if they are not seated correctly the tank will obviously leak--they are easy enough to put back, but the design needs a little more work. Cartos fit extremely tight--better have a steady hand and a lot of patience to wriggle them through the tank, otherwise CRACK! $80 down the drain! A cleaner tasting juice because it's a glass tank? Seriously? The taste of your juice is entirely dependent on the carto you use people.
    It is nice to look at and it's well crafted...I so wanted it to be hassle free...

  7. Awesome

    Posted by Unknown on 20th May 2012

    This is one awesome tank. The quality is perfection at it's best. No rough edges,no leaks and easy to fill. Fits together very smoothly. Juice tastes great in it. Looks beautiful in person. Pictures don't do it justice. Nothing else to be said except pure perfection!

  8. Its the best tank you can buy so far..

    Posted by Pete B, Ocala Fl on 16th May 2012

    I have only had the tank for a few days , It was just released but within that time I couldnt be happier.I am so happy to be able to just pull the top to fill it .The glass mouthpiece is so much better than the any of the metal drip tips have.It is very well built and looks better in person than the pictures.A bit pricey but these are hand made.As far as I am concerned this tank on top of my Provai 24k is the best set up in the world..

  9. Beautiful Tank

    Posted by slickplaid on 16th May 2012

    This tank is stunning. It's everything I have been wanting in the other acrylic/poly tubes, but have never received.

    The clarity of the glass is wonderful, and the juice just seems to behave and taste better. I have no gurgle and it hasn't leaked on me a single time.

    When you go to replace the cartomizer inside, place a drip tip on the end of it, something contoured, and slide it up through the bottom to fit it in without knocking the o-ring out of place. It takes some practice, but once you get it down it's easy. I've even used a 306 with contoured drip tip fit into the top of the 510 cartomizer with success.

    Overall, one of the best purchases I've ever made and looks absolutely incredible on top of my black helix.

  10. The cleanest vape experience I have had yet.

    Posted by Unknown on 14th May 2012

    I had been waiting for the release of these tanks as I love the concept. Mine arrived this past week. I have been using the Duo since it first arrived. This has to be the smoothest, the most clear and cleanest vape experience I have ever had!!! I cannot say enough about these wonderful tanks. You will not be disappointed, they are well worth it in my opinion.
