Let me start by saying I believe Contigo products are the best. This Cortland Chill 2.0, 24oz, Stainless Steel Water Bottle with AUTOSEAL® Lid is FANTASTIC. I took away one star because the features on the website state there is a button lock when there is not. The 24oz and 32oz stainless steel bottles recently ordered a few days before this review does not have a button lock (see photos). Also, the button does not have an indentation like the previous (2020) AUTOSEAL lid I have (see photos). I have big fingers, therefore my finger has slipped off the button trying to support the weight while drinking. And what happened to the ability to open the underside to easily clean the inside of the lid (see photos)?  I suggest to make all the lids with following features: the deeper indentation on the button for big fingers, the button lock and opening the underside for easy cleaning.  For my use, Contigo AUTOSEAL is still the best product on the market.
