Diller Thermal Water Bottle, Coffee Travel Mug 16 or 8 oz Kids Mini Water Bottle Tumbler with Spout Lid, Leak Proof Flask for Kids and Women Keep 12H Piping Hot & 24H Cold (Blue, 8 oz)

Feels great in my hand. Maintains the temperature for hours. I use it to make matcha latte to bring to the gym in the morning. Leak proof mechanism works like charm. Update: three weeks later, and the mug developed a small leak through the hinge (thus downgrading from 5 star to 3 star). I don't understand how it is happening (the seal seems to be unbroken and in place). It hasn't been a hug problem yet, but since I put it in other bags, I will definitely keep an eye on it and will try to keep it upright. Update 2: I finally figured out why it "appears" to leak slightly. The bottom of drinking spout has a tilt, so after taking a sip, a small amount of liquid collects there. After closing the lid, that liquid can spill if you shake the bottle or carry it in a nonhorizontal position. Now I make sure to suck the liquid out first before putting the bottle away and has never had any leaks since.

I laughed when i opened the box and saw how TINY it is! ITS PERFECT FOR MY WORK LUNCHBOX! I was so happy. it seals wonderfully. I read quite a few comments about opening the lid and how hard it was to figure out so i included a video (ignore the dog and cat in the background). It has kept my iced tea nice and cold and even though its fallen over a few times, I’ve never sat down to lunch and found iced tea all over my food. 100% leakproof. Awesome little bottle…thermos…tumbler? Whatever its called i definitely recommend

I needed a small, compact thermos to carry coffee to the office because of a tight teaching schedule this semester. Unfortunately, the thermoses I had on hand weren't quite doing the job. I got the Diller with no preconceptions or expectations and was pleasantly surprised at how efficient it's turned out to be. It did need a bit of a tweak on my part because the first time I used it, I only warmed in with hot tap water. The second time, I used boiling water to pre-warm the thermos. it worked perfectly. On top of keeping my coffee warm and being compact and light, it's also quite an attractive little thing. I'm quite pleased with my purchase.

Keep liquids hot / cold for a very long time. Bought in January and didn't use it much, but the seal is leaking smh.

My husband drinks Calm at night. His old routine was to pour the powder in a glass, stir it with a spoon and drink. This little cup has saved me from going to jail. I would wake up from a deep sleep to hear 'clink, clink, clink, clink' and then 'clang, clang, clang' as he hit the glass with the spoon. Most people would think this isnt a big deal but if you a light sleeper and it takes forever to go to sleep because your mind starting thinking of every little thing in your life or kid's life or world events, you would understand. Anyway back to this cup. I bought the 8 oz one because that is the amount of water needed to add to CALM. Husband adds the water, the powder, closes the lid and shakes away. I don't hear a thing. He drinks the 8oz, cleans the cup and it is good for another night. You could use this for hot or cold beverages. Comes in different sizes. And for me the best part is I won't go to jail for killing an otherwise sweet man. Also, I don't look good in orange.

I purchased this specifically so I could take a cup of nespresso to work. It’s an 8 oz cup but a 7 oz pod overflows it. Pouring out some, and twisting it tight there was leakage from where the lid screws on. This was after I took enough out to put the lid on. The button to lock the lid lands right under my lower lip and feels weird and out of place, not ergonomic. They should have put the bottom on the other side. The hole where the coffee comes out is centered in the opening of the cup instead of near the edge so if it’s half or more empty and you tip it, it feels like you’re going to spill it out of the side of your lips or it actually does spill when you’re drinking. It’s super cute but the design is poor. I ran it through the dishwasher and returned it clearly saying I used it (just once). I’m purchasing a 12 oz in a different brand to be safe as nespresso gives off a lot of foam; I didn’t want to go through the same thing with a 10 oz. I have one of this brand’s water bottles and love it. I work in health care and having a water bottle that completely covers the spout (spout isn’t just clicked down but has a cover) and is leak proof is fantastic. For this cup, a few design changes and different size options and I’d be sold, I like this brand. Nespresso drinkers, unless you’re having. 5 oz or less and like to wear it, look elsewhere.

This is a great travel mug. I like to have an espresso in the afternoon at work. I make it at 8am and keep the lid closed until 1 or 2pm and the coffee is still hot! It's small, perfect for my 2 shots of espresso, and the lid stays sealed and does not spill in my bag. Highly recommend this!

My old (glass) water bottle broke; I used it for green tea in the afternoon at work so I needed a replacement that wasn't glass. This is an adorable thermos, it keeps my tea cold and is easy to open, close, and clean. Now for the strange part: the design. When I take a sip of tea, the open-close mechanism is placed right where my lips are. I am an adult, but a very petite adult. So I think I'd be running into the same issue if I were a child. The lid also doesn't stay 'locked' open, so if I tip the thermos towards me while drinking, it hits my nose. So the thermos itself is sturdy and durable, but the design is strange. The open-close mechanism placement is problematic and the lid tends to smack my nose.

I liked the small size as it was easy to carry around but it didn’t keep my water warm for long. I’d say the water cooled down after about one hour in

Extremely happy with this travel mug, I use it for coffee for when I’ve been swimming and for when I’m gardening. Keeps my coffee hot and I can’t spill it - brilliant!! Oh and yes, it does only hold 1 cup of coffee and that’s exactly what i wanted -perfect!

Parfait pour moi le Thermos est en parti lakeproof mais il coule un peu derrière le couvercle, j’en ai reçu un briser et le vendeur m’en a envoyé un nouveau très bon service merci

Mantiene el agua caliente por 8 horas, es practico, no se derrama los liquidos, pequeño para llevarlo en la bolsa, cumplio con lo que esperaba

Esta pequeño y perfecto, no se derrama mi café y lo mantiene caliente por unas buenas horas!
