I don't know about the exact plywood, but I've had it with my original Tubo and Tetra, then my acrylic Tetra and now my acrylic BAK, I notice zero impact on the vapor quality... I'm usually pretty sensitive to these things? For whatever that is worth!
Agree with your take. Solid wood would have probably been fine and certainly preferred to plastics and aluminum. Plywood and glue however... a deal breaker in my opinion.
Future BAK will be made in all solid wood as well, I think this is just not the season for him to be working on hardwoods in Switzerland yet so there is only the basic more readily available, but keep an eye out for the future (any glue is not in the air path or vapor path and is rated for whatever heat it might be exposed to as far as I know)
But since we're in an "all glass" thread I think the points stand.
Yep, certainly some fresh air over wood as is typical with these, but I think the vapor path is fully pure, and I think in practical use this does meet the standards for an all glass vape that is battery powered... I think to get truly purely securely all glass everything it's really tough to find that electronically
