Love my 401, first PV I bought and will probably stick with it. The size and feel are about the same as a 100 but heavier, you get used to it quick.
The vapor is perfect (with or without VG) for me, and most flavors come through nicely. I couldn't tell you about throat hit as I have nothing but analogs to compare to and the 401 is nothing like an analog, it's nice and smooth and doesn't give me a coughing fit in the morning when I start to vape.
I tend to chain vape so the
batteries go quick, but I got the USB passthru today and I'm loving it.
Does take some getting used to. It is not smoking, just remember that. And give your atty time to break in before you decide whether you like it or not. Take your time and enjoy it, you'll be glad you did.
