I love doubled walled glasses and own a few sets but these are the larger sized ones I was missing. At 16oz these are prefect  for many things. Although these are very big in size they do have a groove mid way up to make holding on to them easy. Its a simple design but are made to be very durable and I would say high quality in my opinion. I have used with soft drinks and beer but also with steaming hot coffee fresh from the pot as shown so burning your hands from heat was not a issue, they truly are heat resistant. Also with these being double walled, condensation was not a issue either. I like that these are both microwave safe and freezer safe so reheating a cup of coffee or chillin a glass for a ice cold beer are not issues. Honestly my favorite set and for the price you can't beat it.
