[This review was collected as part of a promotion.] I was happy to add a couple more glasses to my collection. I thought these would be something different and that they are! The packaging and presentation is nice, magnetic closure box, easy gifting. The glasses themselves are thick and a little heavy. Inspecting the glasses, I noticed no defects, sharp edges, nothing but perfection. The only words are the brand name "JoyJolt" etched into the bottom. In person, the glasses do indeed look like someone has sliced the bottom and the glass is sliding from the base. It's a little trippy but looks totally cool! My daughter is a little OCD and she jokes that she can't even look at them. I already have them in mind for gifts this Christmas, my father and a few of my friends expressed interest in owning sets too. I'd recommend them to anyone really who likes nice glasses, I guess they could be used for more than just whiskey.
