I just wanted to chime in here for anyone still on the fence about ordering that I absolutely adore my precise as well. This was my first mod and it looks sexy enough that I use it everywhere, most of the other mods I see I would be embarrassed to whip it out in public
I use only LR attys and it gives me enough vapor that I can feel it, prior to this mod my e-cig was an intellicig evo and that just didn't have enough vapor to satisfy me, with the precise plus LR it is seriously is better than analog cigs ever were for me.
I don't vape a lot so I only have to change the batteries ever 3-4 hours or so, but even if I was a heavier vaper it wouldn't be a deal breaker for me (then again having a purse makes carrying around a ton of batteries easier) I order the batteries at DealX and they are really cheap so I have a stockpile.
For me personally I like the size of the 10440, i'm going to buy a 6v for at home + battery life next. If I wanted to sacrifice looks for battery life why not get a 6v instead? I personally wouldn't trade the aesthetic factor for longer battery life, then again i am a girl

I wouldn't call a lot of my footwear "practical" either.
I did a ton of research before buying and as far as I'm concerned this is the only mod I have seen where sexiness and simulated HV vaping combine. I am really really exponentially happy with the precise.
