i've been using ZB for 6 months. Most months it's on target. Their customer service is stellar. If they make a mistake, all you have to do is email & they fix it promptly. Only 1 month, I got something in my box that was not in my flavor profile. It was replaced. Actually, it was a tobacco/fruit flavor (I don't do tobacco) that slipped through the cracks and got put in lots of boxes. Probably just an oversight from the vendor flavor description. There is a ZampleBox trading group on Facebook that's active. Personally, I like the variety that Zamplebox offers & they have some very good juices - and, then... there some that I haven't cared for at all. This month, it was Colossus by Cyclops Vapor & Beyond Fruit Custard by Baked Vapes. I'm not a custard fan, but lots are, so I'll be trading those or PIF to someone who needs it. This month I received 87 ml of ejuice. I think this was probably one of the lesser amounts that I've gotten. So, I got a box of good juice, for the cost of a couple of 15ml bottles.
