The v3 is very sleek looking. Thanks for the input
While I love my v3, since the title of this post is 5v, I thought I should point out that the v3 is either 3.7 or 6v. Granted you can use a HR atomizer on 6v, but then again you can also use a LV atomizer on your ego for an experience closer to 5v vaping.
While I understand that variable voltage could be nice and I may have one some day, for now my variable voltage is a mixture of 3.7v and 6v batteries with LR, SR and HR atomizers. So far my favorite is 6v with a standard atomizer. Judging from what I've read it's not for everyone, but then again, I like it rough.
