So after reading around the forums for a pretty long time I decided to order myself a SD, I've had it for 2 weeks now (i think.) I've got to say I can see why there's so much hype surrounding the damn thing, yea it costs a good bit (think i paid 130 euro including shipping) but its definitely worth every cent. So after I've only been using the SD exclusively for awhile now, I've been recommending it to almost anyone I meet, because the truth is I love the thing. This is the only mod that I currently own so I can't compare it to any others (like the GG, Prodigy, and so on.) The device itself chucks out vapor like its a bloody steam engine, and you get a mad throat hit as well even if you're using 0 nicotine carts with it, but the throat hit isn't as significant then but its still there. On average I'm getting about 6 hours of heavy vaping from it so far on a full battery, and that has to be the thing that makes me want to use the SD all the time. As far as the taste goes I still think you get more flavor out of the carts when you're using a DSE901 but there isn't much difference. Oh and the flue cured tobacco e-juice that comes with it is freaking yummy, I absolutely love the stuff. A few things that do annoy me about the SD are, the switch on it, sometimes it ends up, well umm ya press it and it doesn't make contact, but that doesn't happen too often so its all good and its just a minor problem anyway. The battery charger that comes with it takes about 6-7 hours to charge the battery, which is like forever, so I had to get my own from DX and that only takes about an hour and a half or so. Bottom line though it's a great product, bit pricey but still worth the money. It's pretty small for all the work it does, and the batteries and atomizers for it are pretty cheap as well (haven't killed one so far after vaping on in constantly.) Again I'd recommend it to anyone because its a great device, but like anything else in life it's not perfect.
