Hey brewster, have faith friend!
While we wait for angeliques reply, wanted to throw out a line. Not as good a line as Vapor Petes but...
I use 901's and 510's pretty much exclusively. Several posters have mentioned the dreaded "learning curve"!
It is real! There IS a learning curve. Some folks pick it up quicker than others, I know cuz I took forever to get this vaping thing sussed out.
What I learned with regards to the 901.
Keep it wet. If ya drown it blow it out. Then keep it wet.
If your using auto batts, get rid of em. If your using manuals your heading in the right direction. Life's a lot simpler if you can get yourself one of the mods available. Then your battery issues go away and your left with figuring out the atomizer. Whatever your using make sure it's charged. Then keep the atty wet.
Quality control on these things is spotty at best. Total luck of the draw as to whether you'll get an atty that last's a week or a month. One aspect of the learning curve is accepting that the attys and OEM batts are disposable and not intended to last forever.
If you do look at getting a mod, great. Keep in mind that aside from aesthetics, and some of em do look nice, in the end they all do the same thing. They hold a battery.
Main difference between em is flexibility. I use an AdapteveR. There are several others available that work just as well. One device, one battery type and an assortment of one-time-purchase adapters and I can use 801's, 901's, 510's, 306's, 808's and I believe Green Cigs.
Point is, stick with your 901. Make it work. You'll thank yourself for it.
