There are so many drink tumblers and slippers out there. What is different with these 20oz tumblers from Member's Mark? Magnets. What does that do? It changes the structure of the lid, making for less complicated components and as a result, an easier cleaning the tumbler. Oh, and they are dishwasher safe! And there are multiple color combos! The top part slots in a groove on top and the lower part is a minor V-shape and is aligned between two tabbed holes, with the strong magnets keeping them together through the lid, either open or closed. That's it; there's nothing else, no additional holes or plastic on plastic where grime can build up. Slide the top part open and there's a satisfying click as the lower portion opens up in tandem. Same in reverse. The aperture is not overly large, so this isn't a big gulpers best friend, and you cannot use a straw, but this is marketed primarily as a coffee or hot drink tumbler, so less straw, more tilt and sip. The stainless steel lining is a must and keeps hot hot and cold reasonable cold. The padded rubber base is a nice touch. And again, they are dishwasher safe. I recommend these Member's Mark 20oz magnetic coffee tumblers for those who want a set of 20oz sized colorful tumblers for hot or iced drinks that are easy to clean and easy to use.

Great tumblers to use on the go. The tumbler itself is a sturdy stainless steel which I like, the cap is plastic. The sip slot easily slips back, and it has a guard so only a sip comes out which I thought was thoughtful, less risk of burning yourself with hot drinks. Easy to hold and carry around, fits in my car's and stroller cup holder with ease. Love that I can place in the dishwasher (top rack only).

We picked up this 2 pk of MM 20oz Coffee Tumblers at Sam's Club. The stainless steel construction is sturdy and well made. The double walled design works great. Coffee stays hot and ice lasts for hours. The magnetic slide lid is a very special feature. It opens and closes very smoothly. The base fits in a standard cup holder in your vehicle. The exterior stays dry and cool to the touch, so no worries with holding. Cleanup is easy since the lid screws on and off and the slider pops off for easy cleaning. Solid value and Definitely recommended.

Love the blue and green colors in the Members Mark 2 pack tumbler set. The 20 Oz size is perfect, the lid screws on tight and the slide lock works well, easy to clean too. Only small downside is the bottom slip pad can trap a little water but it dries fine if you flip it over. Still great set..

The members mark 2 pack coffee tumblers in tan and brown have quickly become my favorite travel mugs. The colors are attractive, neutral and stylish and I especially like that you can mix & match the lids to the cups. The lid design is my favorite part. It pours the coffee smoothly and doesn't spill a drop when it's fully closed. The material is comfortable to grip and doesn't slip when I pick the tumbler up. My coffee stays hot and my iced tea stays cold! Great product.

Members Mark 20 ounce coffee tumblers are great for more than just coffee. I like to take water with me everywhere, while my husband prefers hot tea. We used these tumblers all day on the weekend, and his tea stayed nice and warm. The lids are nice and tight. No leaks or spills. The sliding tab on top is easy to operate. The best part is that they hold plenty of liquid but still fit in standard vehicle cupholders. The tumblers stayed dry on the outside and are top rack machine washable.

I am very surprised at the quality of these coffee tumblers. There are much better than I expected. A great value for the money. They are a nice weight and they feel good in your hand they work very well. I'm very happy with these and would recommend them to anyone.

These tumblers are amazing! The lids are fantastic and have a great suction to them so they're pretty leak proof which makes it easy to carry around on the go and to work! Great insulation and keeps my cold brew chill! I don't care for the mismatch colored lids on them but otherwise they're fantastic and a great find! I haven't tested out hot beverages in it yet but I can tell it'd be pretty good at keeping it warm based on how cool it keeps my cold brew.

These tumblers keep my drinks warm and cold for a long time! I love that they aren't very heavy. They are also easy to clean. The colors are cute and they don't keep the smells of the drink after washing. I highly recommend these tumblers.

The cups work great and they keep your drink hot for hours. They are slim and easy to carry. The lid goes on great with no issues even when filled to the max. I love the max line so i don't overflow the cup.
