Thanks for your post, it's good to see some actual negatives posted in this thread, for fairness's sake.
I've heard of thread complaints before, but haven't experienced that myself.
The bridge of the atomizer does seem to be at an angle sometimes with these... it is at an angle on the Janty atomizer I am using, but that hasn't caused any problem. If it was interfering with the cart (or melting the cart as illustrated in ceejay's pics), I might try to send it back under warranty.
No LED? We don't need no stinkin' LED! Just a battery waster (but you can get LED versions from other vendors now
).
I've found myself wishing the button was closer to the atomizer side of the battery, which I think is opposite of what you want...
