I bought 4 sets of these glasses at Macy's today and in the process of opening the boxes to check for any damaged pieces I discovered that there are two versions. The boxes are the same, and the designs are the same but one version is heavier, has a thicker rim, and the glass is less clear when held up to the light. They appear more casual than the other version. The version I chose was more formal in the respect that it had a thinner rim, and when held up to the light, was clearer, swirl free glass. Both versions were great looking but I wonder if this accounts for the different reviews. The heavier ones are probably less fragile. I would also recommend checking the rims of the "finer" version. I found a few tall glasses with sharp edges that I traded for perfect ones with the help of the sales lady. They were on sale for 34.99 with another 15 percent off if you use your Macy's card. I think they're gorgeous!
