I’ve had these just a couple days now and love them! Love that it’s 50oz and fits in cup holder, I fill mine with ice and water before leaving for work in the morning around 7:00am and I still have ice when I leave at 5ish, great purchase!

The size is really good and the colors are pretty BUT this does not keep the ice frozen for more than an hour. Very disappointing. I would not recommend these and I wish I could get my money back. You mind as well just use a regular cheap cup because it doesn't work any better.

The cup itself is great but the lid and straw break easily. I purchaed my first 50 oz tumber in July 2023. As of 10/31 I have had to replace the lid and I cannot find a replacement straw big enough not even on the reduce website. This is truly sad since the cup itself is one of the best I have every owned. It outlasted a yeti in terms of keeping ice in the cup. It held for over 2 days in desert climate in August. Just need a much better straw and reenforced edges on the lid to be the best.

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 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!

My coworker has this cup and loves it so I decided to try it. Big mistake. I fill it up with cold water and 1-2 cups of ice around 7:45am and by 3pm my ice is completely melted and my water is no longer cold. Very disappointed that I wasted money on it.

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.

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

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 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!
