This is the second 12 oz bottle of diet Dr Pepper I have purchased where the ring that’s attached to the cap, was not secure…meaning when I went to open it, the whole cap turned & opened as 1 piece. The pop is flat & it worries me to even drink it! It’s hard enough to come by and ridiculously expensive, you’d think consumers would at least get a quality product! I switched to Dr Pepper from Diet Coke because I really like the taste, now thinking that was a mistake!!
