“Not kidding you. I tried for about 6 years to find a flat bottomed mug/tumbler that would keep my beverage hot for longer than 5-10 minutes. Tried several brands - some of them looked the part and were not cheap, including the brand that rhymes with Betty. I about gave up hope when my adult daughter, visiting us from LA, suggested Healthy Human. I tried one - WAHLAH!
These mugs and tumblers are uncompromising in their design and materials. They are very ergonomic and a pleasure to use on a daily level. AND THEY ACTUALLY KEEP YOUR BEVERAGE HOT FOR ABOUT 1/2 HOUR! I love the color options and the included accessories including lids and SS straws with cleaning brush. I ordered the optional Grip-N-Sip slip-on handles - well worth it. Don't waste your time and money on pretenders that fail to keep your beverage hot/cold. HIGHLY RECOMMENDED!
Note: Healthy Human powder coats these in many attractive colors. Although extremely durable, after about 3 years of day-to-day use and regular washing in the dishwasher, a few nicks and scratches did show up (the colors don't fade). There's no way that won't happen over time with that kind of use. I recommend if you want them to stay like new - hand wash and dry. For me - I'm ok with some wear and tear.”
“Excellent quality and perfect size for car holders. Packed well and fast delivery. The large Grip and Sip holds a generous amount. The yellow and turquoise are beautiful colors. We are happy to recommend.”
