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

This cup is the best Traveler I have ever used. Coffee stays hot, no leakage from the lid and lid is easy to put on or off.

Best travel hot beverage holder ever! It’s a simple construction, easy to clean, reasonably priced and keeps your drink warm enough not to be piping hot but very enjoyable. However, most importantly it’s the best leak proof container that I have ever used

Love the product. I had some minor leakage when I filled the traveler too full but it screws on tight consistently and tightly compared to other travel mugs I have used in the past. It is easy to clean and is good value for the mug. What I love most - it keeps my drink (typically black coffee) hot for hours. I work long shifts (9-12 hours) and it has kept my coffee warm from when I first started brewing. It doesn't leave any metallic taste either in that time either. This is the feature that surprised me most as other mugs I keep my coffee in at work actually goes cold after 4-6 hours. This mug is exceptionally different in that my coffee is consistently hot after 6-8 hours. What I love the least - the flip portion does not extend as far back as I would like. It makes it awkward/difficult to drink the last part of my drink without having to twist off the cap and drinking the rest of my drink that way. Not an issue overall since it isn't an issue when drinking initially.

Probably the best coffee tumbler I’ve had. It actually keeps my coffee Hot for at least 4 hours. Very happy with the purchase.

easy to clean and keeps liquids warm. slightest tendency to leak so i wouldn’t throw into bag where it can get knocked over but it’s not a deal breaker.

These are great tumblers. They keep hot beverages very hot for hours. I bought 4 as Christmas gifts and the recipients (siblings who live in a different state) have already thanked me for such a nice gift.

Flip top lid is not leak proof. You can test yourself by firmly closing the lid, turning it upside down and watching your coffee drip out. Disappointing as that is the reason I paid a high price ($30) for this mug. I travel a lot and always have my mug with me, it's important for it to be leakproof. I do know it's possible to make a flip top lid leak proof, as I carried a bueno mug (basic Target) for 7 years that was delightfully leakproof and cost a fraction of this mug. I'm not interested in the 360 lid, they get moldy and gross and difficult to clean. Otherwise it's fine, nothing special to make it stand out.

I really like the Miir traveler because among the insulated mugs I have used that do not require you to remove the lid to drink, this mug is the easiest to drink from and the most leak proof.
