STILLSMOKE9,
Not trying to be contrary but, my 901 experience is just the opposite!
I'm new at this, but don't think there is yet an ecig that you can pick up and get a good, consistent hit each and every time.
You want to see tempermental?, get yourself a 510/Yeti/DuraC. (no flame intended to 510 lovers, but I do actually have a love/hate relationship with my Yeti !)
I started e-smoking (with a 901 kit) around April 1 and found it wasn't quite enough to get me through a typical Saturday night. Monday thru Friday, on any given workday/evening, it was fine. But sitting around a BBQ grill on Sat. with (smoker) friends, beer in-hand, the 901 just wasn't "quite enough".
I bought a Yeti and for the first few days it was great... then it started getting finicky... went back to the 901 a few days, picked the Yeti back up, fine, then finicky again... up/down, up/down for several weeks.
I finally decided to just go back to the 901 as my main, use the 510 occasionally or for backup... just received shipment of 9 901 atomizers and 30 carts. I'm vaping on one now, tastes great, good hits...
Please, just don't give up and pick up analogs again (like I did for a while).
Good Luck,
