Thanks for helping
The one I bought was this one https://www.vapeclouduk.co.uk/collections/starter-kits/products/innokin-ez-watt
I heard great reviews online and purchasing one from their starter kit just seemed to make sense. I was originally looking for like a really thin pen thing that I had seen on an advert but I was advised by live chat that they weren't the best and that I should look at one of these.
I got some free juice with it and I think that was a 6, whatever that means.
I hope this information helps
