Reusable Insulated Double Wall Acrylic Tumblers with Lid and Straw 20 Oz, 12 Set Package, Clear

Couple of issues:1. One cup arrived cracked in the box. I admit I did not bother spending the time and energy trying to get a replacement.2. Several cups cracked during normal use3. The threads on the lids are poorly designed and the lid will cross thread more times than not4. Lids leak around the edges
