I bought these cups after a coworker raved about hers. The ad claims to keep ice cold for 50 hours. I could not get mine to hold ice longer than a couple of hours. I find that my cup is rather on the heavy side as well. These are supposed to be just like the Stanley cups. Just cheaper. I think I will throw this one out and go back to my Yetti or Rtic. They hold ice and have the handle and are a tons lighter. Just not my cup of tea.

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 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

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.

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.

Great cups that stays cold for 50 hours. Kroger has the purple reduce cups.

very large tumbler

Good size. Fits car cup holder. Drinks do not stay cold for over 3 hours.

I love Reduce! Why I own 9 of them!!! I can tell you they are worth it! They do keep drinks cold! I do smoothies and it keeps them cold all day.

Does not keep cold. My wife uses one at her desk job, and it doesn't keep cold for 8 hrs, let alone 50. Our son works for the USPS his doesn't keep cold out in the heat for even 4 hrs.
