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.

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 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.

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.

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.

I have 5 of these in different colors and would buy more! Keeps drinking ice cold for more than 24 hours. They are also comfortable to hold. And the price... perfect.

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.
