Zojirushi SM-SD48BC Stainless Steel Mug, 16-Ounce, Silky Black

Q: How does it know whether to keep the drink hot or to keep it cold?

Elon and Google have been working on this for a few years. They have finally managed to engineer AI that attempts to detect whether you want it to be hot or cold. The mug pairs with your phone through Bluetooth and that allows it to share your drink status with the whole world.

Q: What's the difference between SM-KB48TM and SM-SA48?!

There are four variables in choosing a Zojirushi mug. (1) Exterior color - self-explanatory; (2) Interior finish - either 18/8 stainless steel or nonstick finish; (3) wide mouth or regular mouth width; and (4) volume size - 12, 16, 20 ozs. You have to read the description of the particular mug to see what it has. The number and letter nomenclature for the various mugs is indecipherable to a lay person. I own the SM-SA48-BA regular mouth, nonstick coated interior, 16 oz size in black; and the SM-KHE48AG wide mouth, 18/8 ss interior, 16 oz in blue. I prefer the wide mouth variation which accommodates wider ice cubes and has a larger pour spout; and the 18/8 stainless steel interior for less odor retention and better liquid taste - IMHO. BOTTOM LINE: Read the description of the particular mug you are looking at to ensure it has those features you want.

Q: is this spill proof? i desperately need a travel mug which does not leak AT ALL.

Spill proof and doesn’t leak! It stays hot 48 hours. Just love it. I have 5 of the same kind with different colors, 20 oz. Highly recommended! The best insulated vacuum mugs! Hot or cold! ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
