The ice will stay till the next day and they do fit into any cup holder in any vehicles but was expecting them to be a little bit smaller Easier to manage while you are driving.

These are absolutely amazing for taking to my kids sporting events, Disneyland or even just using around the house. They keep my drink cold and my husband and I absolutely love them!

These cups are huge. I love that they are sturdy and well designed. However, I had to return them because of their size. My hubby and I like smaller cups so I purchased their 32 oz cups without the handles. We love them.

Great product keeps drink cold and great size to carry water. Well designed by having straw, lid, and handle feature. I would recommend this product. Does fit in a car. U can fit two but got to have a little bit of space.

Love these cups! I wanted a large insulated cup to take every where( road-trips, office, school) These fit in my vehicle cup holders. They keep my water cold all day. They look & work great.

Absolutely love them!

I have all the cups. Yeti, Stanley, RTIC, etc. I have them with straw lids, flip straw lids and regular pour/open lids. This review is based on this tumbler vs all the others. 1) I do like the size and the handle. 2) It did not fit in my cup holders. 3) It did not keep drink cold for the day let alone 50 hours. (I drank mine right away so I was good but hubby does not drink fast like me so his ice melted and his water was ‘cool’ but not cold after 9 hours.) I feel like it’s a fine cup for someone that drinks water quickly and drinks a lot. I try to get 100oz in a day so I do like this if I’m sitting at my desk. With all of the choices on the market this is not a great option. I love that they tried to redesign the shape into something that might fit some cup holders but it needs work in the actually keeping ice and keeping drinks cold department. This was not part of a promotion. I paid for my cups. I won’t return them but they aren’t great.

Ice all day

After searching extensively online, I eventually chose this pair of 50-oz tumblers for 3 main reasons: 1) The competitive price, even with tax & shipping included; 2) The lid design which positions the straw in the center, but also has the flip-cover over the edge sip opening; 3) Lastly the fact that the base still fits my vehicle’s cup holder. These keep my water and the ice I place inside cold for an adequate amount of time. The only thing I didn’t care for was the extra large diameter straw that is suited best for drinks with the boba gummy balls. For any other beverage it just flows way too much liquid. In fact I ended up switching out the straw for a slightly smaller stainless one that as I found online. I highly recommend this set of two tumblers over all others at this same price point.

Ice doesn’t stay cold for 50hrs.
