I'm about a month ahead of you gameover.
I started out with a 901 mini from Meltrex.
His service is top notch and everyone will tell you the 901 is a winner.
I would too, except that, although it works really well, it's a MINI!
I get a twenty minute break every hour. I generally smoke one and sometimes two regular cigs per break.
By the end of the 8 hour shift.....6 breaks....... I've gone through both batteries and God knows how many cartridges.
I am hooked on e-cigs.....but within 5 days I ordered a Kissbox Classic Penstyle.
The draw is easier.....smokes great, just like the 901 if not better, and I believe is a better alternative to actually replacing real cigs.
Two cartridges, two or three batteries, and some smoke
juice will carry you through the entire day.
This cannot be said of the Mini's.
They are great for backups or a few hours out, but to replace cigs fully you need a full sized apparatus, at least I did.
Don't regret either purchase but the only thing I would have changed would be the order in which I bought them.
My next purchase is a Generic Penstyle so my Kissbox will get a rest from time to time.
Looking for one with interchangeable parts that will work with the Kissbox.
Keeping the batteries charged has turned into a bit of a juggling act.
I hope this helps and please realize that I personally want to completely replace smoking real cigs........if you just want to offset your real smoking than the 901 would do fine, but to last you all day and night your gonna find, as most do......you need something FULL sized and not just a MINI.
