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)

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.

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.

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

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.

Well made mugs. For in the car cup holder and. Hold the temperature very well. Excellent value for the price! Happy with the purchase.

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.

Excellent mug, well thought out and designed. I use to pour tea into smaller cups, first container that I have used that it doesn’t drip when pouring. I’ve never had one that didn’t drip. Also when you snap shut and turn upside down it doesn’t leak. Also the way it’s designed it has indents for your fingers for better grip and it’s perfectly aligned with the pour hole, nice touch. Looks beautiful as well I got red. I rarely write reviews.

This does keep my morning coffee hot. The color is very nice. The lid closes tightly so I can be sure it won't leak, though I would not toss this into a bag full. The plastic has started to splinter and break off around the top and on the lid. So far it has not impacted my ability to use the cup, but it is something to consider especially if you want to gift this. Overall, I think it is a good value for the price.
