So I picked up a Vamo from electronicstix.com on 12/20. I recieved it and have been using daily since 12/24. The problem lies with the first battery tube that is attached to the head. It is simply pressed onto the head and on my device this keeps coming off. This thing works PERFECTLY but this battery tube issue is pretty major. It's almost to the point that it is falling off. I've emailed the vendor today to address the issue and I'm currently awaiting response. Anyone else run into this yet?
