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 Member's Mark 20 oz. coffee tumblers are great quality! They hold a good amount of liquid, and they keep beverages hot or cold for hours. The sliding tab design is smooth and very easy to open or close as needed. Everything is dishwasher safe, which makes cleaning quick and simple. I like the weight they have, they feel sturdy but not too heavy or bulky. The solid color design is simple and clean, which I appreciate. I definitely recommend them, whether you're looking for something to hold your morning coffee or keep your water cold through the day.

Liked everything about them. The non slip rubber on the bottom and the lids are great at work. The lids keep you from accidentally spilling and they came apart easily so it could be cleaned. Kept the coffee nice and warm well past lunch time. Recommend to all and would buy if looking for more.

These adorable 20 ounce travel coffee tumblers are good quality. I love that they come in a variety of colors. They are well made, stainless steel, top rack dishwasher safe, and have a max fill line printed inside so you don't over fill your cup. I also like that the closer tab on the top is magnetic and easily comes off, as does the the tab on the inside cover, for a more thorough cleaning. I think they would be perfect for hot or cold coffee.

Very convenient. Keeps my drinks at perfect temperature. It last long at its desired temp. Light weight and easy to hold. The design is sleek and beautiful. They come in gorgeous colors. Great value. Fits perfectly in my car and strollers. Easy to clean and care for. They hold 20oz.

These tumblers do not leak even when turned completely on their side, even when turned completely upside down! The outside of the tumblers do not get hot or warm at all and stay comfortable to hold while the inside stays hot. The lid screws on and has a magnetic sliding tab that closes to keep the area that you drink from closed when not using. This magnetic sliding tab creates a vacuum like seal and really keeps your drink hot, you can hear it when you open the slide letting the air in. The colors are super cute and stand out from others. The shape allows you to grip the tumbler securely. The lid comes apart so you can thoroughly clean it so no hidden or hard to reach mold. To top it off this tumbler keeps my drinks hot all day.

This 2 pk tumbler is an excellent product. It keeps my and my daughter's coffee hot while we both are in office and they fit my car cup . It is easy to clean no spills and I personally feel a very thought out product. Go ahead and get one and you won't regret.

Very nicely made. Keeps liquids hot for hours. It works best to put hot water in first and let it sit for a couple of minutes. Pour the water out and fill up with your hot drink of choice. It has nice texture on the outside of the mug. It is also easy to clean(dishwasher safe)

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.

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.
