    All of my purchases have all been very fast and well packaged, sticking with the 2-3 days delivery time.
    Thank you for the service and the help.

    Brilliant mod

    Posted by Unknown on 8th Feb 2018

    Brilliant mod. I love the fact that is has a built in battery, so you don't need to bother buying any batteries along with a charger. isub V tank goes perfect with this mod too.

    Definitely would recommend

    Great Product But dont do what I Did!

    Posted by Unknown on 21st May 2016

    This is a bloomin good mod. By Firing quickly it solves a lot of leakage problems. One word of warning buy a case. Putting it into your pocket with a tank on and working all day can uncentre the contact point. Which leads to resistance problems...not the mods fault but the operators. I place an o ring between between mod and tank to stop the tank moving from side to side on the mod now. Ok short term solution workaround. Will buy another coolfire 4 plus and a case. Excellent product innokin

    Scrap my 4 star review

    Posted by Martin on 16th Feb 2016

    Double reviewing here but not coming with an ego adapter doesn't warrant an entire star. I bought an adapter from here for $2? and my old clearos work fine now. Moving right along to the amended review. With a Nautilus Mini or iclear 30s, this battery produces flavours I haven't experience yet and I've been vaping for almost 3 years. Maybe it's the combination? doesn't matter really. Sturdy battery with amazing results. Looking forward to .5 ohm and other options.

    In short, the power in this battery is amazing and there's only one reason I didn't go 5 stars. Not sure if this is the same with every order? There was no eGo adapter in the box and almost all of my tanks are eGo. Well it gave me a reason to try the iclear 30 (I think). I only went to 10 watts before it was too much for me, peaking at 9.5/10? Amazing product and amazingly good value. I should mention that trying a different brand adapter didn't work.

    Fantastic Quality

    Posted by Rats Bum Leather on 31st Oct 2015

    Brian's customer service is second to none! Fast shipping and great communication.
    I bought 2 of these. Typical Innokin quality build. They are strong, sturdy and look great!
    Matched them with the iSub tanks (only $19.95!!) and they look great together.
    Love the on/off switch at the base, more mods should be looking at this feature.
    The curved design fits really well in the hand, with fire button in easy reach.
    The only con is the screen is to small. But works well.
    Overall a Great Mod!

    Amazing mod

    Posted by Bob on 9th Aug 2015

    I ordered the steel coolfireiv and it looks amazing with the isub tanks or any steel/glass tanks.

    Very good build and very easy to use. The on/off switch on the base is great and unique compared to the clicks of most mods.

    Having the built in battery I think makes this a better choice than the kanger sub box.

    Design is great and fits nicely in hand, zero rattling.

    Being VV/VW means you can do just about anything with this at a low price and unless you want to get into Temperature Controlled stuff you wouldn't ever need another mod besides this thing!

    Also thanks Vapeking as this device arrived at my door in 24hrs of making the order!

    Slick Finish, Excellent build quality,

    Posted by David B on 20th Jun 2015

    I recently purchased this beast(in blue) along with a Aspire Nautilus mini, and I'm amazed by the amount of clouds it produces for being such a small device.

    It fits in my hands nice and snug and i use Medium size gloves, you almost can't see it.

    Only bad thing i could say is that when you accidentally scruff the shiny blue cover you can really see the marks, would be nice to see a case coming soon.

    All in all a Great little mod I would recommend to anyone, my mate is

    Really good quality Sub-Ohm mod

    Posted by Lukas Bartko on 16th Jun 2015

    Picked this mod up for my fist sub-ohm experience, I must say i'm blown away heaps of power for sub-ohm tanks.

    I've been using the subtank nano (0.5ohm)and it produces heaps of vapor. Really comfortable in hand, Buttons are very clicky but feel good.

    Got mine in Black the finish is nice and feels durable and well made. The Screen looks nice but is a little small. I love the mechanical On/Off switch on the bottom more mods need this feature.

    Loving it and i would recommend this mod to anyone new to sub-ohm tanks and looking for a cheap but good quality mod.
