i have a 401, but it has the new style widebridge atty's with it (evo type attys?, i'm not sure but they are better). It gives decent throat hit, decent vapor, but the flavor is unmatched by any of my other styles... I feel like i'm gimping flavors by vaping them in anything but the 401 and if i REALLY need to judge a flavor, the 401 is the tester.
It does have a 7sec. cutoff, but, there's no delay b/t another draw after i hit cutoff.. i still don't know why but it's like this with all 3 of my batteries....
it's still my go to, just has more of the attributes that i want (got through a whole DAY of work, and into this evening, still going) on one battery... When using it as a dipper, it's just about perfect (more vapor and it'd be perfect)... I also have a chrome'd, blingy 401, and it gets the most attention when i show folks what an e-cig is (compared to my others)... Doesn't look like a cheap, fake cigarette, but a classy PV type device...
