I love the shorties for a few reasons, one is that they are auto and I like to be able to just pop it in my mouth and vape and still be able to do something else with my hands, like type this post. Two is their small size, they are the lightest thing out there to hang in your mouth and they are easily pocketable and have that analog feel to them.
The downside is the shorter battery life, but I don't care because I like to have multiple flavors loaded without swapping out cartos, and I don't mind carrying a "pack" of shorties - I'd rather have a "pack" of shorties than one XL or a regular battery with a PCC. Multiple charged
batteries is better than one battery and a PCC IMO.
As far as how well they vape - they are 3.7 volts, just the same as an XL, it is just that they die faster, which as mentioned above is solved by having a pack of four shorties in your pocket. So they vape the same as an XL if you're on a fresh charge.
So the only other real issue is your preference for air flow, and air flow characteristics have changed on the models whether you are talking manuals, autos, shorties, or XLs. I really really liked the air flow on my older shorties that had the notch in the battery post, but now they don't have the notch anymore so the draw is a little tighter and a little louder. And even that is subject to change depending on the size of the holes on the battery which as far as I know hasn't been permanently set in stone by V4L yet so I can't know what the air flow on a shorty you might order would be like. Regardless, it is still my favorite battery, unless you count my auto pass-thru 'cause I'm a fan of 5 volts.
Give me 5 volt shorties and I'll sell my
mod and literally carry a pack of those things.
Those are the pros and cons IMO.
