CS COSDDI 12 oz Stainless Steel Vacuum Insulated Tumbler - Coffee Travel Mug Spill Proof with Lid - Coffee Cup for Keep Hot/Ice Coffee,Tea and Beer (White)

This cup has been my go-to cup for the past year and a half for coffee. It keeps my coffee hot (when sealed shut) and is very portable since it's on the smaller side. I'm surprised that the metal hasn't been dented or the paint hasn't been scuffed, either. It's easy to use when driving, too. This is an example of a cheap product that certainly isn't cheap by any means! The only thing I will say is that the little piece of rubber that's used to seal the cup shut (the one that blocks the small air hole on the lid) is finally starting to be soft. I noticed it was rubbing off when I was washing it. However, with how cheap this thing is and how long it took to get to this state, I'm completely okay with that.

Good cup, keeps hot for about an hour. Easy to hold, to drink and never spill.

I have always hated the oversized coffee thermoses so I was ecstatic to find this. I got the cute two tone pink & white one a couple of months ago and the paint is still perfect. It is lightweight even with coffee in it, and more importantly it fits in my cupholder. The shape of the cup and the texture of the paint ensures that it never slips as well. This wonderful cup keeps my coffee piping hot for up to three or four hours; I even have to take the lid off to let my coffee cool down a bit so I can drink it. Very easy to clean, and the seal on the lid is 100% secure. Also the mouth is the perfect size for sipping so my mouth doesn’t get flooded with searing hot coffee! Most importantly… it isn’t oversized.

Great travel mug for keeping your drinks hot. Fit in cup holder great, and overall a wonderful mug. Only 4/5 stars because the paint does begin to chip over time. Not too big of a deal, as the mug is still usable and good.

The thermal mug keeps drinks hot for a very long time. It is very convenient, beautiful, and practical. However, please note that it cannot be washed in the dishwasher — it should only be washed by hand. I have already ordered three mugs. One of them did not close very tightly, but I requested a replacement and everything arrived perfectly. Thank you, I highly recommend it.❤️

I bought this tumbler over a year ago and decided to buy another one. I like everything about it but most of all it didn't leak. The lid has a small flip over cover that snaps into place never leaks. This new one was slightly different. The flip closure did not snap closed. When I turned it over and water poured out in a small stream. I decided to fill it with hot water to see if the lid material would soften and mold itself to seal. I made sure the cap was firmly screw in, closed the flip cover firmly on the lip, then turned the mug over. Water came out again but then slowed to a trickle and eventually stopped. The next day, same test, leaks about 2 drops per second. Both old and new kept hot liquids hot. Started with 207 degree hot water. One hour and 15 min later about 147 degree. Still hot enough. I like the tumblers. I have confidence that one will not leak either while in the cup holder while driving or in my gym bag ( would still place it in a medium plastic bag ). The other one that leaks, place in a cup holder or in your hands only.

I bought this for my husband for his work! He needed something non spill, and this is perfect! The lid fits great and keeps his tea hot. The color is really pretty, and its a perfect size! It seems very durable! I would recommend this item.

Update: I’ve only had this cup for a short time and haven’t even dropped it or anything but the plastic around the rim cracked. Not sure if I can return or get a replacement but definitely disappointed. I did like this cup a lot but the plastic cracking takes off 2 stars Love this Cup! It’s a perfect size. I was really excited about it being leak proof so I turned it upside down and it instantly spilled BUT that was my fault. I didn’t realize the mouth piece has 2 clicks. One for just gently closing it to keep the heat in while drinking and one to actually lock it. One I figured that out 10/10. Keeps my tea hot and no bad taste. Color is so cute. Exactly like picture
