Uhg, I type slow and the server went down

At least I have learned to "copy" before I hit "post reply" so I am going to post anyway, better late than never ......
You should check out the Smokestik subforum
SmokeStik
I love my Smokestik, I have 2 Pitbulls, a Hendu and 2 Royales. I agree with everything that mwa102464 said.
The cartomizers come pre-filled, but only in 2 flavors, regular and menthol, various nic levels 0 to 16?, and are quite good, the cartomizers can be refilled with any juice you want. Although, care should be taken because if you have juice dripping from the cartomizer it could drip into the auto battery and wreck the battery or "switch", but I have never had a problem. They have some type of fiber fill wadding. You can just keep buying replacement pre-filled cartomizers(Smokestik would prefer this so you keep sending them lots of money) . The cartos are nice and they do not "burn" very easily and if you re-fill they seem to last a long tome.
The batteries have a nice auto "switch" that works well, as was stated above, and they have a voltage of 3.4v under load, which is better than the 510 minis but not as high as the kr808d1 batteries.
It is a very nice, quality product, looks cool and "feels" a lot like a regulal cig in use, although heavier.
Negatives: battery life: Hendu ~2.5 Hours on a charge ; Pitbull 3.5 Hours on a charge
Can get pricey if you don't refill your own cartos
No Personal Charging case
With only a 2 or 3 hour battery life, if you are going to be away from home for an extended time you need to bring a bunch of charged batteries with you or a means to charge them.
Threads are rn4081 and is not the most compatible with other products as the more popular 510 or kr808d1 connectors
Not the most cost effective option out there and not a "super high perofrmance" PV
I also have an Infinity Mod from Notcigs which is wonderful, but I still bring the Smokestik with me and use it when I am out and about.
--- I also have a Blu w/cartomizers and I haven't used it since I got the Smokestik have have no desire to ever use it again - While you can find people who like it - it is an inferior product in every way.
Good luck.
