I haven't tried anything other than blu, but I think people get ...... because they have to fiddle with it at times. There's a learning curve here, but people don't like that because they don't like thinking in general either.
Not sure how you can make that post if you haven't used anything else. How can you accurately compare?
I personally like KR8 stuff, but I don't turn people off 510s due to the sheer number of satisfied users for that and the fact that I haven't tried one.
And there is a learning curve with all ecigs. To paint people that don't like the blu as not thinking is a bit off imo. I haven't used a blu either, but I don't doubt the negative outlook on them when there are so many that hold the view that it's an inferior product with poor customer service.
The Blu uses carts. And the carts are MUCH smaller than the 510 carts. You will have to refill them more frequently, so it's actually more hassle. They also have shorter battery life than the 510. Not sure where you got the impression that the Blu is hassle-free. It's anything but.
If you want no-hassle for going out, try cartomizers. You can pick up 510 cartomizers, or you can get the Kr808D-1 (which also has the benefit of having better battery life than the 510).
Walk out the door with 3 or 4 full cartomizers and a couple batts, and that's it. I just take my Kr808D-1 PCC. It has 2 slots for cartomizers, and obviously a slot for charging or storing a battery. And then, I have my assembled Kr8, with a full charge and a full carto. That will keep me going all day.
You beat me to it MN. The blu seems pretty similar to the M401 and it just doesn't cut it for conveniance one the go. cartomizers do. Pretty much no fuss no muss.
