I picked up the Stay-Chill Slim Can Cooler in Galaxy Black and it does exactly what it promises. The double-walled vacuum insulation keeps my seltzer cold noticeably longer than a plain koozie, and the screw top lid means no slipping. The non-skid base is a nice touch on glass tables. It fits 12 oz. slim cans perfectly. Just remember it's hand wash only. The ergonomic grip feels solid, and the stainless steel build seems durable. A simple, practical buy for anyone tired of warm drinks.
