For me, smoking and/or vaping has always been about style and taste rather than just a way to get a nic-fix.
I like my e-cigs light, compact, and clean which is why I stick with the KR808D1 stuff. I have some 510 batteries and tanks, but I find them to be bulky and messy. To me, mods are even bulkier and messier. No offense to any serious vapers out there who I am sure will disagree with me, but as far as I've seen, if you use a mod, you have to carry a heavy, bulky piece of equipment around with you, and usually a bottle of juice to boot, whereas a shorty or standard 808 battery and carto can be carried in your pocket or in a small case. If a huge cloud is your thing, a mod is the way to go, but you can get some pretty decent clouds with 808 batteries and small clearomizers if you know the little tricks. The manual batteries tend to produce bigger clouds, but I personally prefer the automatic batteries as I drive a manual transmission and work with my hands, so I need something I can vape on without having to press a button.
This is my first post, and I am still a bit of a vaping noobee, but I would welcome any comments or suggestions. Thanks all!
