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 (Green)

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.

I was in a designer of kids cups for my company and I I thought of something like this cup. It is the most perfect cup I ever used and when you close it tight put in a bag. It doesn’t leak at all and it keeps my coffee hot for a very long time.

This tumbler keeps coffee hot longer than expected and the lid doesn’t leak in a bag or cup holder. Size is perfect for travel, and it feels solid without being heavy. Simple design, easy to clean, and does exactly what it’s supposed to do.

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.

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.

This is a great coffee tumbler. My daughter got this for me in mint green and I bought 2 more as gifts for the holidays. The insulation of it keeps your coffee hot for a long time and its a great size. For me it's perfect for work because I get distracted and usually my coffee gets cold right away. I recommend it and the price is reasonable.

Great product. Holds heat for hours. Fits perfectly in our all of our vehicle cup holders. Easy to clean. I dropped one on my kitchen floor and no dents. Happy with my purchase!

The sipper lid is a bit hard to close fully, and if it’s not sealed properly, it can cause quite a bit of spillage. I tested it using hot tap water, and after one hour the water was still hot, which is impressive. I’ll update more after using it longer. *** This is Update: the doesn’t stay hot after one and half hours. It was lukewarm. It can only keep hot liquids hot for one hour to one and hour. Not more than that. Didn’t try with cold liquids. I wanted this for hot coffees.*****

This coffee thermos is great. Not only does it look nice, but it keeps coffee hot, and is easy to clean. It’s pricey, but worth it in my opinion.
