I like the form factor of the shorter length, its easier to get around with that's for sure. But I am an all day vaper, and the bigger battery would be helpful. I have 1 mini and 2 regular size 2.5s and the difference in battry life is huge. That's my issue! My Radius gets me through most of the day... i think the tube form coupled with the bigger battery might be a tad large for me. I am going to try it out with my dragon... i have an extension for that, i will give it a go for a day and see before i buy.
