Count me among those with no problems with my old or new sets—and I have a ton! My only "complaint" is that I wish they'd stop releasing dozens of new colors and instead sell all the fun new pieces or sets in some of the colors that were popular for many years. I totally understand that we all have different preferences, but do we really need 18 shades of blue and green or lids with a glittery finish just to be different?
One thing I've noticed is that Chris has stopped reminding people about how to properly set up the lids on the glass pieces to accommodate the wider silicone seal; if she went back to doing that, I think it would help a lot of customers. It really only takes an extra second or two (to describe it or to perform the task) and is the only way to ensure the lid is successfully sealed.
