“Really - if you want a bullet-proof ergonomic mug that KEEPS YOUR BEVERAGE HOT/COLD - just buy one of these Healthy Human tumblers. I have 4 - 12 oz. mugs and 2 - 20 oz. travel mugs. I buy the grip-n-sip handles. They come with Stainless Steel straws and no-leak tops. There are other cool accessories available. I like them so much I gift family members with them. You won't be sorry!”
“A surprisingly roomy and convenient vessel for my daily protein smoothie! Easy cleanup and fits just right in my cup holder. I have yet to try a hot beverage in this cup but feel as if it would be perfect for hot cocoa or cider, minus the straw. Beware, the lid comes off easily so this is not intended to stay in place if you tip it over!”
