Glasses seem to be sturdy -- although they do have air bubbles in them -- but Wayfair sent me a box that was someone else's return (?).  (The box had a label showing another person as a sender and Wayfair as a recipient.)  Wayfair asked me to send back the glasses via fedex in exchange for new goods.  I don't mind doing that but that's an extra errand that could've been unnecessary had Wayfair sent me new products in the first place.  2 stars for Wayfair experience (and the glasses themselves could be 4 starts.)
