I have the Glasvin Champagne and Lehmann machine made Jamesse. Unfortunately, the base of my Lehmann glasses (machine and mouth blown) developed ugly etching/clouding after a few rounds in the dishwasher. The etching worsened the more the glasses were dish-washed, so I have a set of 12 Lehmann that are “guest only” 
. Am I the only one with this problem?
The Glasvin are thinner, and even though they look teeteringly tall, the base is wide and stable, and they fit in my dishwasher. Also, @davidkong’s customer service is great. None of my Glasvin champagne glasses have broken so far, and I will purchase more if there’s a WB day deal.
