30 oz Stainless Steel Tumbler By BaySea - Vacuum Insulated To Keep Drinks Ice Cold Up To 24 Hours And Piping Hot Up To 6 Hours - 100% Satisfaction

Love these tumblers. 30 oz is a good size, it fits fine in my car and truck cup holders and it really does work! I filled mine with fine hot chocolate. Then got called away from home. Came back 4 1/2hours later and stil had fine hot chocolate. In another occasion I poured a cold drink. Ice cubes and drink stayed cold and ice was still left after 9 hours. They don't sweat and when I accidentally knocked one over I got a little splash from the drink opening but the lid stayed firmly on 🤗You can drink right out of the cup but I did buy some aluminum straws on Amazon and l like using them. I like the price as well.

Love my cup. I use it all of the time. It keeps my water cool even siting in the car in the sun. This wasn't intentional, but I forgot it once. Came back, the very top water was warm (not hot) but just below was cool and refreshing. I have had no issues with the. The seal on the lid is wonderful. I have dropped the cup on the floor, and you will get a small dribble with a closed lid, but it wont be the entire contents. I take this with me everywhere. It is a little heavy and can be bulky to carry. They have handles available. I ordered one, and I wasn't happy with it, so I will be trying different ones. I get complements on my cup all of the time. They are surprised that it isn't the more expensive one. I wanted a smaller one for my husband, but they don't offer in the 20 oz.

This is a great cup for hot and cold beverages. I use mine mostly for water to take with me in the car or at bedside overnight. Both areas prove to have plenty of ice the next day or after sitting in a hot car. It also doesn't spill IF the drink opening is closed, which mine rarely is. The only reason for 4 stars is because I find it heavy and a bit cumbersome without a handle. But I also have arthritis in my hands so might not be a problem for many. I do like that it holds more liquid than my previous cup so it's a trade off. I have also noticed a tiny squeal it emits when drinking from it at times which I guess is from such a good seal. It doesn't bother me but there are some picky folk out there that it might. Basically, this is a great cup for the price and does the job as promised.

I have been using my tumbler for work with cold drinks. I filled it up with ice & kept it at my desk until I was ready to use it. The ice wasn't melted one bit. As long as the drink is cold when poured into the tumbler it keeps cold for a long time. I still have ice when I get home at the end of the day. Mug is large so I have ordered a handle to make it easier for me to hold. Great find.

They do keep drinks cold and hot, only 1 problem I have noticed, the lid leaks when I have something hot in the cup. It is only doing it on one of the cups and it stops after the hot beverage is done and I put a cold beverage in the cup. I think the "gasket" might stretch out due to the hot liquid? I don't know but it isn't worth returning the cup. I am pleased with my purchase

I absolutely love this tumbler. It does keep drinks and ice in it for a good 6-8hrs. I would have given it 5 stars if it closed properly. I always have to keep it upright else my coffee pours out even when it's completely closed otherwise everything else is absolutely perfect

Dont like emails, this company keep bugging me with emails. The price is right, don't know if it will fit in my car, too wide and heavy to carry every day, I think, but I don't think it keeps cold for 24 hrs. I drink ice water with ice all day, use a straw and by the afternoon I need to put more ice.

Take it with me everywhere. Keeps my coffee hot & my sodas cold.
