Goes over 4 days before a recharge, Bit slippy to handle, apart from that I find the Innokin Coolfire 1V a very good vape.

Great Mod
Monday, 20 February 2017  |  Kathy

Tried various different 'pen' type ones but they did nothing for me. Have been using cool fire iv for almost a year now and havent smoked one cigarette. for me, this is the best mod going. have tried other mods too, but always go back to my cool fire iv! ordered another mod from Vapourlites, blue colour. colour is great, delivery fast and brilliant price. amazing service and would definitely order again from this company.

Cool Fire IV
Saturday, 26 November 2016  |  Stefano

Great mod if you're looking to move up from e-cigs/shisha pens. Well made and tough (already dropped mine a couple of times). Good vape and adjustable voltage and wattage lets you fine tune depending on e-juice. Great service from Vapourlites too. Fast delivery and well packaged. All-in-all, a good starter kit from a great supplier.
