The wide bowl really does pull the nose forward on lighter reds, and the narrow rim keeps everything concentrated instead of spilling out. I've run them through the dishwasher a few times already and they've held up fine. Twelve glasses is plenty for a full tasting group.
Bought these for a wine night with friends and the narrow rim made sipping noticeably cleaner than my old tumblers. One arrived with a faint scratch near the base, but at this price for twelve I'm not bothered.
