After reading and watching many reviews I finally decided to upgrade to a cheap mod and tank setup, and found the one I wanted on www.amazon.co.uk
The Aspire Zelos 50w Kit Nautilus 2 Tank (Black). it's a great little mod and tank combo, and does exactly what I need to move on from real cigarettes. The Nautilus 2 Tank has adjustable air flow so it can be turned down to give you that tight draw like you'd get from a real cig. Open up the airflow and crank up the wattage and your doing virtually mouth to lung.
The Nautilus 2 tank is a very neat looking tank, but it has its drawbacks for me. One being, because it's a top filling tank and toe top cap has a integrated cover that slides over the glass tube, it's quite difficult to grip the thing to unscrew the cap /Cover to refill it, it's very smooth with no knurling to gain any grip. Its small, only hold 2ml of juice, but that's the size all tanks will be soon due to the new laws being introduced.
Apart from that this thing is fantastic, and the mod itself is extremely easy to operate, has loads of functions if you want to explore, or use different tanks. And a built in 2500mAh Battery so you'll get a lot of vaping in between charges.
