Query: Trevis Insulated Glasses

Don't waste your money. These glasses are of poor quality and I paid $10 each for them by the time I paid shipping. They do have condensation on the sides plus one of them nearly cut my lip. When I called to tell the company the glasses were real rough around the edges, they asked if I could file them down. I was shocked by this question. They did send me a replacement, but they were all blue and I had ordered the assorted colors. I am not happy with my purchase and do not recommend these glasses, not at $10 each. Maybe $2.50 each. I was considering buying the larger glasses, but not after receiving these.
