sorry, i can't edit my posts... I was wrong on the date I received my order from absolutelyecigs: I actually received that on 1/4/10.
As far as reviews of products: I like the DSE901. It gives good vapor, flavor and sometimes throat hit (I think some of this is due to the liquids though), most of the time it's just very smooth. I go through 2 batteries a day and god only knows how much juice. I think I have to top these off every time I go out to vape.
On the M402, haven't used it much, but it does seem to give pretty good vapor and flavor as well. Auto Batteries don't last nearly as long as the dse901's though. We got a couple of the M401 Manual batteries as well and I have to say I don't like them. I don't get as much vapor from them as I do the 402's. I don't know if this is because of the type of battery or if I don't know how to use a manual correctly...
The M201 Penn style - love it. Battery and juice in cart last all day pretty much, great vapor and decent throat hit.
Still looking for that perfect analog replacement though. Want something I don't have to drag on for so long, that gives exceptional vapor, throat hit and taste as well.
