I've looked at the CE5 reviews on YouTube, but I found that the reviewers preferred the CE4 (I could be wrong, maybe someone on here with more experience could set me straight) but the CE5 has a higher wick? The CE4 lower wick produced a better vaping experience??
The crown tobacco is amazing; my favourite too, I could eat drink and vape that forever. But at a price of £1.72 a cartridge, and 4 cartridges a day (because you're so right - they don't last as long as their marketing would have you believe) - it was costing me more than stinkies. That's the dilemma I was in finding something like that as liquid. I was guided to here by another forum member who loved it too:

and I placed an order on Saturday. I'm just awaiting it to be dispatched with the long bank-holiday weekend, so as soon as it arrives I will let you know whether it tastes like the crown tobacco or not! I'm excited about it turning up
Though, as I said earlier - I tried the Espresso Mocha at Liberty Flights yesterday and that was pretty close to the Crown Tobacco - smooth dark coffee with a dark chocolate taste, soft and luxurious - beautiful.... but I need a clearomiser to appreciate it!
