These tumblers are well insulated. They really do keep hot stuff hot and cold stuff cold. I made hot chocolate and tried to take a sip an hour later and severely burned my tongue. It hurt. Well done!

I love these and will order more to replace my assortment of drinking glasses. They hold heat and cold (ice) very well, and I don't need a coaster since they don't "sweat". I don't think they'll fit my car, but with the wider bottoms, they are less tippy in the house. I'm wild about them, other than the fact they are made in China.

These are a generous 16oz size however the teardrop shape means that it's not going to fit in a car cup holder. With the virus that's going on that's not a big deal right now but it will be something that I would miss in the future. These will be used daily by myself and occasionally by visitors to my home for adult beverages as well as for iced tea and iced water to be kept at desk side. I love the fact that they go in the top rack of the dishwasher because 90% of insulated mugs will not and you end up having to hand wash them. These look like they've been well-crafted using a sublimation process for the colors and patterns on them and I imagine that these will hold up for years with gentle top rack washing. I'm looking forward to many years of service out of these; the pretty patterns and the very small price on sale make me feel like this is a good deal. I truly wish that they had some kind of a gripper on them because they're very slick which is going to make them hard for small hands so I imagine that these will be mostly for adult-sized hands to hold.

I was very disappointed when I received my tumblers. The navy blue was replaced with sky blue, so I ended up getting two sky blue. The packaging was interfered with, so I tend to think that the person packing the items literally took the navy and gave me when he/she didn't like. I am not happy because I did not get what I paid for.

Lid leaks - coffee all over the seat.

Got them today. They really do stay cold & the ice doesn't melt as fast. Good buy.

These cups are awesome. Larger than I expected with vibrant colors. The price was affordable. They are sold out so I have to wait to buy more.

These tumblers are beautiful, and they do keep my coffee hot for a LONG time. However, the lids leak, so don't knock over your tumbler.

Purchased last month for use around pool. This cup kept a drink, with ice, totally chilled and ice still intact, overnight.

I have purchased several insulated cups but these cups are wonderful. Talk about keeping your beverage cold for hours these are the tumblers.
