Hi all, newbie here...
I was lucky enough to have received my Darwin on Wednesday, maybe because I live closer to where nHaler is located (or just lucky?). Anyways, I tried it and immediately LOVED it! The amount of vapor, the flavor, and the consistency of the whole experience was nothing like my past e-cigs. The only problem was, I blew out two of the Drip-O-Mizers for no apparent reason. The highest setting I used was at around 8W (mid-way point). The first Cart may have been defective since it didn't work from the start. The second one that died worked for perhaps 10 minutes and then boom... the voltage jumped to 11+ and the atty simply didn't work anymore. Odd thing is, everything appears to be fine now using my other carts (same model as the ones that died one me). Sent Drew an email explaining what happened, hoping to find out I wasn't doing anything wrong.
Also, the connector seems a bit odd with my Darwin unit, so I wanted to compare with other Darwin owners before concluding it's defective. While the unit works fine after I screw in the carto, the thread on the connector seems extremely tight. So much so that I can only screw it in maybe 1/3 of the way. One odd thing is that the round-protruding part in the middle of the connector area seems loose. Depending on how much I have the connector turned (from off to on position), the position of that center piece moves toward the side. Not sure if that's getting in the way of my not being able to screw the cartos in further. Finally, when I turn off the unit with my 510 carto in place by folding the handle in, it barely clears the body of the unit (lower part of the carto either touching or nearly touching the unit). This may imply that the connector may not be properly secured, but I really have no way of knowing.
Any input from other Darwin owners will be appreciated. In the mean time, I do think that Darwin is a fantastic product that provides one heck of vaping experience.
