MiiRFlip Traveler 16oz - Double-Wall Vacuum Insulated with Leakproof Flip Lid, BPA-Free Stainless Steel Construction, Insulated Tumbler for Hot or Cold Drinks

Terrific design. Flip cap solid snappy. Well made & well worth the money. I'll get another one.

Excellent size, color, and quality. Love the functionality of the lid that makes it spill proof.

The 12-oz insulated mug is not cumbersome and is very effective in keeping coffee hot for a long time. The cover seals well...absolutely no leaking. It is easy to open and to drink from. I would buy again.

I am really impressed by how well this MiiR keeps liquids hot for a long time. Very sleek, good-looking design. My only issue is that the lid can be a little awkward to drink from. When opening the flip top, the part that opens, I'll call it the "tab", sticks up and presses against my nose while drinking. I thought it would lay more flat.

Practical and durable water bottle and keeps water cold for many hours.

I thought this was in a virtual tie with Zojirushi for the best mug on the market. Advantages: Big opening makes it easy to fill and to add big ice cubes (I use it for iced coffee), it’s simple to use and clean, and the lid is easy to use.But after several experiences of dumping iced coffee out of my (thankfully waterproof) backpack, I came to realize that it wasn’t me being forgetful, it was this mug spontaneously opening. If you plan to always keep it upright (in your hand, on the counter, in a cup holder), add 1 or 2 stars. If you might have it in a bag or a backpack or need to lie it down (like in an exercise bike beverage slot), you can do better.I even once once brushed it while it stood on the padded floor of a gym, and watched it gently fell over and pop open.

I love MiiR bottles. They keep beverages hot or cold for hours. I've put water and ice cubes in mine and had the ice remain frozen more than 24 hours later, and coffee and tea stays hot all day. The flip top lid locks securely and prevents spills even if you shake the bottle vigorously, and the subtle non-slip texture on the exterior helps keep the bottle secure in your hand. Finally, the shape and the matte finish give them an elegant look and feel. These are by far my favorite insulated bottles. I do wish they were dishwasher-safe, but you can't have everything.

It still leaks and even opens on its own while in my bag. I’ve spilled my coffee 3 times now!
