I've tried an Rn-4072 and DSE801. I like them both - the 801 is a little bit easier draw. I can't say the differences between them, to me, are that significant. I have never burned a cartridge with my 4072, but I've only burned one with my 801, so this isn't that significant to me either way.
I greatly prefer pens to 510 myself. The only real drawback the pens is their size - but the larger carts and batteries are what makes them such a great choice, so it's kind of a neccessary evil. Also be aware when you're first using that the performance seems to improve after you break them in a bit.
Are all DSE801 the same?
What I mean is I can get a DSE801 a lot faster from myvaporstore since I am in NY then from David yang and they are both about same price with shipping
Where did you get your DSE801 from?
How did you find your throat hit overall?
