I have mixed feelings about it. I like the performance/vapor/throat hit, but it's equal IMO to the Pilot/m401. Has a bigger cart that's easier to top off, so less frequent and easier refills. Manual battery option, so doesn't have same sensitivity issues as m401. The auto
batteries I've got for it are sensitive like the m401, but not as much. Has a portable charging case, which I love.
So what's the hold-up from total love? Reliability and parts price. I had my 1st ever atomizers die with the Dura-C. 2 in 2 days. I have Pilot atomizers that have been under near continuous heavy use for over 6wks without a hitch. Avg m401 atomizer price last I looked was around $10. Avg I've seen for Dura-C/Titan/etc. is $15. $5 not much of a big difference, but if on avg I get 4+wks of heavy use out of a $10 atom and I only get days to a couple wks light use out of a $15 atom...well, I'll use the $10.
I got used to and pretty fast at topping off the Pilot and I never did get the large capacity carts, so while it's somewhat nice with the Dura's bigger carts, not a make or break issue to me. Sensitivity of the
batteries was only a problem for me with strong wind, so got used to keeping the LED of the m401 cupped in my hand.
The PCC case is the thing that really sets the Dura apart for me. So I'm hoping the dead atoms were a fluke. Give me a month of steady use without a failure and I might fall in to the

category. Until then I reserve judgment.
