My 900mah twists disappointed me when I first got them.
They lasted about the same as my 650s had which is ok as long as the charging one is ready to go when needed.
They do keep up so that was not an issue.
After a week of rotating the two in and out they started lasting a lot longer.
I bought the 900mah because of the VV as I supposed I would be upping the voltage as compared to my old 650s.
I was right as most stuff burn between 3.6v and 4.4v in my Pro-tanks using 1.8ohm coils.
Now my Pro-tanks burn right to dead empty and use about 1.5 batteries to do that.
I clean the coils ever three days or so and re-use them at least 5 times except for an occasional dud.
I NEVER replace the wicks as I have no clue as yet as to any of that and already saving so much money along with my health I am pretty happy.
But I will probably end up going there just because I dearly love to fiddle with stuff.
