My husband just got a 901. My mother and I both vape these. He has only had it for 5 days and has burned through his atomizer already! His battery life is also much shorter. I was worried about this as he has a real heavy draw to begin with. He really enjoys his PV and is discouraged. Is there a better model for someone like him. Our house is "new" to e-cig's. We don't know much except that we love them.
