Review on Libbey 13 oz Crystal Coffee Mug Set of 6 - Warm Beverage Mugs by Jesus Gallagher

I love these mugs! Would give 5 stars. A few months later one had a torn seam and the bottom fell out while I was filling it with coffee. Another one broke the same way today. So out of 6 cups I have 4 left. I know clear cups are popular these days, they're heavy and easy to hold. Hope this issue got fixed. I want more, but I don't want to pay for something that will break sooner or later. I'm the only one who uses them in the house, so I know it's not because they're not taken care of. UPDATE: I never mailed the above and today the 3rd fell apart at the seam like the others. So I got 3 out of 6. So annoying, not to mention dangerous.
