Query: Used to be good, but not anymore

I bought a pair of these glasses back and 2005, and was very pleased. The quality was great and the price was low.Well, manufactures must have changed or something since then because I decided to buy another pair and am very disappointed. The build feels very "plasticy" and I could tell right away they are not the same pair I bought a couple of years ago (even though it is the exact same product in my Amazon history). They aren't even the same glasses in the product pictures, nor do they come in the leather case the previous pair came in. Instead they come in a little felt sack.I'd suggest spending more and getting something of better quality.
