Style - Super Mini, USB charger.

Battery life - 6-8 hours with 10 vapes then rest 30 mins. 2.5 hours non stop vaping.

Vapor volume - low to medium on the prefilled cartos that come with it, medium to high on refills with PG juice

Flavor - extremely light on the prefilleds from the supplier, up to you with refills from juice.

For a super mini, I rate it 7 of 10, it could have better media in the cartos and they could have a bit more flavore in the prefilled ones as well as a nother drop of juice to make better vapor on prefilled but, for a DIY/ juice user who wants an affordable mini, it is a good choice.
