I got a 1 and 3 year old and leave my SSV on the bar at all times but don't use when there running around. I hope MJ is regulated when they get older here. Too me the usage is not the problem its where or who u purchase MJ from.
From my personal experince, I'd wish I got the SSV first, I own both at this point, and prefer the SSV. And I'm also trying to sell my DBV $120. I have no idea how to trade cash online yet. I will post it on the seller forum. until then If any one is interested e-mail me.
Go with the Silver Surfer Vaporizer, its more efficient than the DBV. If you look hard enough and use some promo codes you could find one for 250 , plus the womerns love the look of the SSV. For 50 even head on over to the vapestore and pick up a VG ,hey its christmas spoil yourself a liitle.
