Does it's job without extra frills
I needed an insulated cup for to and from work, and this fits the bill. I like that there's a minimal interior ring because it's a pain to clean ones where that's more pronounced.
Nice tumbler
I got the gold/yellow colour as it was on sale and I liked it even more than I thought I would. Fit excellently in the Subaru cupholder. Drank hot tea and then left it in the car for a few hours and came back to decently warm tea still! Lipstick wiped off the material which was great. Easy to clean.
Bummer
Very leaky lid. Lotta coffee speckled shoes and car seats. Am looking for a substitute lid option through Miir, but no luck.
Fabulous tumbler!
This is the coolest tumbler! I haven’t tried hot items yet, but when I left it sitting in a very hot car, I came back to icy cold water. Excellent purchase - and great chartreuse color too :)
Great product!
This mug holds hot or cold temperature drinks amazingly well!
All purpose tumbler for on the go
Using this insulated tumbler is my small way of protecting the resources of our world. It travels so well, even empty, I keep it in my car for last minute stops at the coffee stand. It keeps the drink hot or cold and the lid fits snug enough to not leak.
Simple Functional. Just right,
Simple and light to carry or toss inside or in an outside pocket of even a small pack. But the pleasant surprise was insulating quality while driving in a hot car on a 92+ trip across Missouri and Illinois. Starting with plenty of ice with water poured over, it still had some ice after being refilled from my water bottle several times. Alert: it didn’t have the advantage of air conditioning. Seems well made. I do not plan to drop it from a great height or use it to pound tent pegs.
Good value
Fits under a Keurig and in a cupholder in the car. Keeps coffee hot. Inexpensive on sale. Checks all the boxes
Disappointed
Like the look BUT it is not as well insulated as my 9 year old Thermos cup that has been run over by a commercial lawnmower.
Great mug
Great mug that is easy to drink from and clean. No intricate parts that can trap liquid and be difficult to clean. Keeps beverages cool and hot long term. This is my family coffee mug
