If you plan on using an on/off switch I'd vote for the side but if not I'd say on top. If the production model is the size of the beta unit it will be pocket friendly and a side mount won't work without an on/off switch. I loved the form factor of the beta it fit like a glove in my hand. I recommend the largest drip cup you can design for the final product. I've owned plenty of devices that just use off the shelf washers for drip cups and they don't work, juice everywhere. The Reo Grand is a good example of a good size drip well. Of course you know my feelings on the switch but you've already addressed that. Mike what are your plans for protected the juice feed plunger/switch? I'd like to see a larger window/opening for view remaining juice, these old eyes can barely see inside the beta design. Will there be a low voltage indicator on the final design? My only other concern would be protecting the voltage adjustment thumb wheel from juice.
All in all I think the VVPV is an outstanding device and vapes great. Great job Mike. By the way have you decided on a price yet?
