I love the size and durability of this 50oz tumbler. It keeps my ice water cold for a full 24hrs. I fill with ice over half full and fill to the brim with water and I have ice cold water all night and day. I do wish there were cute patterns or at least a purple one. For cold water longer, when not in use I do keep the tumbler in my freezer during the summer months without the lid on and then put cold inside when ready to use so I have very cold water when outside and I don't have to refill often with the size. I've had for 2 yrs now and it is still holding up like new

I ordered these as teacher gifts and really love them. The colors are beautiful, the 50 oz doesn't make the cup feel way bigger than the typical 40 oz, nice handle, there's a rubber grip bottom that keeps the cup steady and prevents denting, you can track the amount you drink by glancing at the measured markings in the cup and you can use straw/sip or gulp methods. It's definitely a great competitor for the Stanley and at a much more reasonable price!

Does not keep cold as long at it says. I bought these cause I kept leaving my other brand tumbler at work. They do not hold cold at all. Filled with ice and water at 7:30 am and at 12:30 pm most of the ice is melted. My old tumblers held ice over 24 hours. I do enjoy the bigger capacity and wider straw, but not worth to buy again.

I bought this set of tumblers because of the price. I love them because they're perfect for me. I love the size. I love the cap (I take medication 4x a day so I can take the straw out and seal the hole) or I can drink from the straw. I don't need it to fit into a cup holder since I leave it by my bed and I don't need my drinks ice cold, it stays cold enough for me throughout the day.

Just received this morning. Filled with ice and it's now 10pm & I still have plenty of ice. They are a bit heavy but no problem since there is a handle. Gonna get a lot of use with these! I am diabetic so I drink lots of fluid daily. With the size of these it means I don't have to refill as often.

I was looking for a decent sized tumbler to help me increase my daily water intake, this exceeds my expectations! Holds up to 50 oz, keeps my drink ice cold and fits in my car cup holder. I can even hang it off my stroller when going for walks with my toddlers. Highly recommend!

I bought 2 sets of these They are a waste of money. I like my drinks very cold. I fill the cup full of ice, within 2 hours the ice is melted and the soda is watered down. If drinking water it might be okay but still not kept cold like advertised. These cups are very heavy. If I had the barcode still I would take them back.

Got these for my wife, they are horrible. The cup itself it nice , but they DO NOT hold ice well. She filled the cup 3/4 ice within 3 hours it was nearly gone. The cup gets extremely cold on the outside. So it definitely doesn't hold well. I would take them back but I already threw the box away.

It works great as keeping liquids cold (don't know about hot) and fitting in a car drink holder. I have a couple of issues with the tumbler : 1. If you place it on a flat surface it easily tips over 2. The lid is not very durable - was removing the lid and it slipped out of my hand, it fell to the ground and broke into pieces.

I was excited to find these big tumblers so I wouldn't have to refill my water several times a day. Such a disappointment! They do not hold ice all day and they sweat like crazy! If I lived closer to the sams club where I bought them, I would definitely return! I love the size and the handle, just wish they didn't sweat all over the place.
