Excellent Value ModReview by david
The Cool Fire IV is excellent value for money in the 40W range. Build quality is good and OLED screen clear. It pairs very well with the iSub (great with matching colours) or iSub G tanks. Fits well in the hand and has really good battery life. Vape counter feature handy as well. (Posted on 30/03/2016)
Best I've had. Review by @m
Another quality product from THIS site. Old innokin MVP2 still working 2years on. But this is better, long way better. Holds charge longer higher watts/voltage if needed for high VG. Low for my preferred Vaping in 50/50vg.

Safety off buttons. Three presses and off vape button and completely off sliding button for piece of mind and travel. Many safety cut out features. This is so highly rated across the net. You will not be disappointed. Bought second spare now. Its that good and the old MVP2 in bin.

Lovely finish with no finger prints all over and Feels ace in the hand. Fits in Palm it's a mini size really. Highly mpressed and a great OLED screen, its clear as, even with my 1970's eyes.... Thanks again Another satisfied vaper. Support this site. You will not believe the quality of service (Posted on 04/03/2016)
Great ModReview by Chill
Decided to get a 40w mod to use on a variety of tanks, Kanger Protank 3 / Genitank, Aspire Nautilus, i Sub G. After reading / watching loads of reviews I went with the cool fire. Delighted with the purchase, build quality excellent and works a dream with all my tanks. Vapours customer service and advice excellent as with all my purchases from this site !!

Great Box!Review by Ferny
This is the first box I have bought and for £38 I payed it is well worth that, I've had It for around 3 weeks now and there are no problems with it, I'm very happy with the purchase and would highly recommend. This is very much a 5* product!! (Posted on 21/07/2015)
Amazing!Review by Jaime
Had to have a new battery when I upgraded my tank as I going even further into the sum-ohm spiral. Went for this one as it goes down to 0.3Ohm. The battery is easily the best I have had. The freedom to use it whilst it is charging is a great plus. The size and shape of it is perfect as it fits snug in your hand. I am using with the new Triton tank at 0.4 ohm and is brilliant. Would definitely recommend! (Posted on 20/07/2015)
AwesomeReview by Trigger
Decided to switch to sub ohm, so needed a new toy. Went with this and so glad I did! Great product, manageable size, useful features, especially being able to vape whilst charging! Great finish on the product meaning the appearance is excellent also. Now sat in the garden looking like a custard scented volcano!

Have to commend the service received also. Any orders I have placed have been promptly despatched and beautifully packaged. Great customer service also. A pleasure to deal with (Posted on 15/07/2015)
