Slims dont put enough power on attys;they are very feeble.
If you think you will buy one and use it (i.e. enjoy it as say,an eGo) you are dreaming
I sometimes play with them a bit with my Mark-T (and right now The Fog) but they always feel like the
batteries went dead fresh off the charger
They work for like 3 puffs then its over
When I screwed the The Fog on an eGo battery,I instantly knew why its called like that...dudes,that lil thing put my UFS and Ody to shame!
In fact,it puts everything I own to shame....
