I don't really give my buzz pro much special treatment. It's been on boats, to the beach, in the woods, summer heat, frigid winters (i plow using the tractor and it's usually along for the ride), etc. I just try to keep the really harsh stuff away from it like soaking it in water, leaving it in the baking sun for hours and hours, or getting dirt and sand in it.
With that said though, I'll pick it up with wet hands as long as it's not a huge amount of water, and it has gotten pretty hot before. Other than that though, I let it bang around wherever - obviously I try to keep it in a place where that won't happen but if it gets dropped or knocked into stuff it's bound to happen and it can take it. I'm more worried about losing it than breaking it.
I've learned to be more cautious of the cartos/attys/tanks that I screw on there.. broken a few threads off of tank 510 connectors by leaving my buzz standing on the roof of cars and watching it do a headfirst dive into the pavement.
