Query: Great glass for a (fill in your drink) on the rocks

These double walled glasses are awesome for an evening drink, the ice seems to last a little longer than just a regular glass, but it might just be me trying to excuse paying for these glasses. Anyway they are very nice, they don't feel fragile or cheap and they have a good weight to them. I definitely plan on ordering a few more pairs, but I will wait until they are a lightning deal again. This make a great addition to a home bar!
