CS COSDDI12 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’ve been using this 12 oz stainless steel tumbler for a couple of weeks now, and I’m genuinely impressed. It keeps my coffee hot for several hours and my iced drinks cold even longer — perfect for commuting or long workdays.The design is sleek and minimalist, and the black finish looks very stylish. The size is ideal for fitting in my car cup holder or tossing in a bag. The lid seals tightly and is truly spill-proof, which I appreciate because I’ve had no leaks, even when the tumbler tipped over in my backpack.It’s also super easy to clean, and the stainless steel interior doesn’t retain odors or flavors. I’ve used it for coffee, tea, and even a cold beer — all worked great.Highly recommend this mug for anyone who wants a reliable, portable thermos cup that looks good and actually works.Tip: Preheat or pre-chill it with hot/cold water for a minute before use to get even better insulation performance.

Love this cup! I use every morning and holds up well. I was hesitant because I thought the hole was too small but it’s fine. Keeps coffee warm and really cute. Easy to clean and is a good price point over other options.

I bought these stainless steel coffee tumblers for the car, and they’ve quickly become a morning essential. They fit perfectly in my cup holders (no rattling or tipping!), and the lids are secure with no annoying leaks — even when I hit a few unexpected potholes.They keep my coffee hot for hours, which is a lifesaver during long commutes or weekend road trips. I also appreciate the sleek, modern design — they look great and clean up easily. The insulation works both ways too, so they’re great for iced drinks in the summer.If you’re tired of lukewarm coffee or flimsy plastic cups, these tumblers are the upgrade you didn’t know you needed. Highly recommend!

Great for on the go.Sometimes leaks from the breather hole.Great quality; love the different colors. Hold a normal size cup of coffee. Love the closable lid, easy to drink out of. Almost spill proof.

Keeps coffee hot, nice size cup ,easy to handle

I got the Dark Wood Grain cup. Looks great, has held up well, got it about a year ago. Use it at least 1-2 times a week. Hand washed only.Keeps coffee hot! I always preheat the cup with a little hot water before filling it with coffee or tea etc. That helps the drink stay hot longer.As long as you pause a sec to truly put the lid on CORRECTLY and tighten it properly (don't over tighten) & push the mouthpiece down hard til it clicks, this thing has not dripped a drop! My husband and I will use it interchangeably, and neither one of us has had a leak this whole time. Not bad for a $10-$15 cup!

Nice size, stays warm or cold, washes well.Also have a purple cup like this

I love everything about it, but it's just a tiny bit too big for me to be able to comfortable hold it in my hand while on the go. No problem to just pick it up and drink it and put it right back down. But if I was walking around with it, I get worried about my grip. I'm 5' 2" and have small but chunky fingers. I had a similar product that fit perfectly in the past, and hoped this one had similar circumference.Otherwise, it's great. My coffee stays warm, it is easy to pour into, close up, and wash. It stays sealed and does not leak. It's a great product for it's price range and would be perfect for the vast majority of people out there.
