  1. Nice looking but junk orings

    Posted by Unknown on Mar 15th 2017

    I purchased 3 of these loved the design, after 3 days the first tank would leak within a few seconds after a fill up, changed orings with the spares they give you, again after a few days leaking again, opened second tank all was good until a few days later it starts leaking as well, leaks from where the glass sits on the base, this thing need better orings...haven't opened the third tank, kinda pointless I guess...

  2. Nice tank

    Posted by Christine on Mar 4th 2017

    I got this tank to use with my Nugget so that I could order coils VP carries and I like it. I do have issues with leaking however I think that may be operator error.

  3. Great tank!

    Posted by Tonya on Feb 12th 2017

    I've been using this tank for about a week now. It's not a tank for mouth to lung use, which is how I vaped. So I switched to direct inhaling and I'm so glad I did.

    I haven't had any problems with leaking in the tank. It's been very solid. As of now, I can't complain about the coils either. I'm on day 8 with the coil that came with the tank and the flavor and hits are still great, so the coil is outliving the week I thought it would last if I was lucky. I'll review the coils on their own page after I use at least one more.

    I definitely recommend this tank.

  4. good flavor

    Posted by Rick Ulstad on Feb 7th 2017

    It has great flavor but has issues with leaking.

  5. solid tank, sub par coils stock coils.

    Posted by Daniel Heinrich on Jan 8th 2017

    The tank itself is great, seals well, shorter than most...wider to make up for it. But the serpent coils barely hold up against 40 ml of juice before they start producing burnt hits even running at 30w which is 10 less than recommended, if I had been firing at 40 I suspect this would have occurred sooner, the saving grace of this tank is that it can utilizes 2 other brands of coils that will hopefully outlast the stock ones.
