I think the majority prefer the RN4075 it burns slightly higher than the 901
901 is alot smoother smoke... while i find the 4075 has a much better throat hit!
I actually thought it was opposite that people prefer 901 attys due to... build quality, maybe.
I've been putting in bunch of 4075 attys in my Ruyan Direct cart all day long... I have 2 4075 attys, and 5 901 attys - as I do want to use up the 901 attys before I buy next bach of attys... but another part of me is saying "why should I stick with something that I'm not too fond with?"...
Forgive me if this has already been addressed, but, do the SD, Prodigy, etc. shorten the life of an atty?
Well, I haven't noticed any significant decrease in atty life from SD. Don't have Prodigy nor other mods, so I can't really compare. But with any other attys, my opinion on longevity of an atty is nothing but a crab-shoot. Get lucky, you get one that lives few months. Get unlucky, you'll get your atty shot in few days.
My current atty that I'm constantly using with my SD is little over 2 months old. It's still running quite well - although the performance seems to have dropped a little bit, and even after cleaning, it's not performing as well as it used to. On the other hand, one of the attys that came with my SD died in about a week. I have other 901 one that's going strong, about a 3-4 weeks now. So it's rather eratic, to be honest. Not because of SD's bigger battery, but more or less due to the fact that atomizers' built quality isn't that consistent nor great.
there's no real difference in build quality as for the 901 vs 4075
it depends on if you like a smoother vape or a harsher vape ?
RN4075 seem to be the winner and most popular at the SD Forum!
If I'm not mistaken, 901 has more exposed wick which makes better contact (supposedly) - and some sort of rubber ring inside, which helps preventing flooding issue a bit. Perhaps I'm wrong. (and it's not first time either! LOL)
I can only speak for the SD, and the answer would be "Not at all."
I've prematurely killed more attys on a 901 passthrough than I have on an SD.
The biggest physical difference between the 4075 and the DSE 901 (both of which can be used in the SD), is the position of the element/bridge. The 901 is higher in the atomiser, and should be used only with the DSE 901 carts (one piece, all black). The 4075 has the element lower in the atty, and should ideally be used with the 4075 carts (black, with a brown extension), or the Dura carts (all black, but with a round mouthpiece, and the same depth as the 4075 carts.)
The biggest performance difference is the draw -- the 901 is easier, while the 4075 is a bit harder, possibly due to the difference in the position of the element.
Hmm.. any reason that why carts are not interchangeable? When I put 510 cart (or 4075 cart) in 901 atty, it just dig a little deeper hole, but it did seem vape relatively alright, and vice versa.
The 4075 also runs at a slightly higher temperature than the 901 so the throat hit is increased.
just my opinion, but the 4075's seem to stay more efficient for longer, the 901's seem to drop off a bit after a while, though still work. maybe i should clean them more, but for 'hits per mile', i'd say the 4075's have the 'sports wheels'
I prefer the RN's but have found them to be very supplier sensitive - some are better and more durable than others - given I thought they all made by the same company, that seems odd?
Sure, you can switch 'em, but the shorter 901 carts won't come close enough to the 4075 atty to make that indent, and the longer 4075 on the 901 atty needs to be positioned exactly right over the higher bridge or it won't seat all the way. Personally, I can't be bothered squinting into the atty and matching up the two -- and folks who don't realize there's a difference (like me, in the beginning) get frustrated when the 4075 cart doesn't insert all the way, or when the mismatched carts don't produce as good a vape. YMMV, of course.

I see. Thanks for your info.
Well, I did measure some of my carts (various and same models) - and for some strange reason, some of them are taller, some of them seem to be shorter etc. What's even crazier is that some of them are actually for the same cart model - like single flat hole model 901 carts, sometimes vary in height - usually fraction of a mil or so.
510 cart and 4075 seems to be indeed the tallest. Luckily, I haven't had any wicking problem with 901 double air-intake with my 4075 atty... which is my favorite 901/4075 cart for topping off purpose... but I'll watch out for the future, as my next 4075 atty, might not make a good contact with it as you've mentioned.
Stickelss, not sure why you chose to resurrect this old thread just to start flaming but that's not going on here.
And to you others, you would have been better off just reporting the posts rather than responding in kind. We're not going for this back and forth bickering. Please take it elsewhere.
Thank you,
Lu

I got my ScrewDriver yesterday - wow, what can I say, great service from the producer, dispatched next day, arrived the day after.
The device itself is easy to use, and has a lovely feel to it - I actually don't care that it doesn't look like a cig. It's function more than makes up for that trivial issue. It just works - that is all I can say, no buts no ifs, strong vapour any time and highly suited to being refilled from a bottle. I like the face that it is solid, and I can keep it in my pocket, and that I can take a draw on it when I please without worrying about the battery.
I tend to hold it like a pipe - pushing the button with my palm, it is unusual but highly satisfying smoke - much better than real cigs, and much better than all the e-cigs I have used.
Brilliant.
