Ninja, Travel Mug, Sip Perfect 12oz, Brings Hot Drinks to Sippable Temperature in Minutes, Stainless Steel, Leak Proof, Dishwasher Safe, Metal Insulated Tumbler, Green, DW1203GN

This is the best leak proof, sipping lid design travel mug I've ever purchased for drinking coffee and I have purchased quite a few, numerous name brand ones and others that are not. It keeps my coffee at a great temp. I have never burned my mouth using this mug as I have done many times in the past with other brands. I also use it for keeping a beer cold and again, perfect for drinking along with keeping my beer too. The mug has a nice rubber base that's removable and does a excellent job of keeping the mug from sliding if for some reason you sit it sown on a slopped surface. My only negative comment I have with it is, it's fat which I'm no fan of. I travel a lot and carry it with me in my computer bag for grabbing coffee at hotels and for use during my work day. I rent a lot of different name brand cars from the airports and there have been quite a few that the travel mug will not fully fit down in the cup holders, so be aware that could be an issue. I do recommend it, just keep in mind the diameter (3"), it may not fit your cup holder if you plan on using it as a daily travel mug.

This is now my favorite coffee mug!!! I love ninja products. My whole kitchen is basically ninja. Anyways the coffee mug...its works so well from the first drink to the last. No burnt mouth and maintains the temp very well! I have not run into a time where it was cold to drink. I definitely recommend purchasing this!

I have everything ninja. At this point I wish they would sponsor me because I love their products so much lol and this mug is nothing different than amazing. I had a yeti and when I learned ninja made a mug I had to buy it. It doesn’t keep your coffee blazing hot but I like that. It helps your coffee get to a comfortable drinking level and you won’t burn your mouth trying to sip coffee It feels premium like all of ninja’s products. It feels sturdy and quality feels great. It has a rubber base which helps if you’re a little clumsy. However, even if you tip it over, it’s leak proof and does not spill everywhere. My only issue with this mug is that the base is thick so it does not fit in my car’s cup holder. However, I have extra room by my cup holders and it fits just fine. However, if you just have cup holders with no extra room this won’t fit. I love taking my coffee to go and this is such a great product. Anyone buying this would love this mug and you know what you’re paying for since it’s made by ninja.

Edited to add: It doesn't keep drinks as hot as I'd like. My Yeti does a better job. I do like that it's easy to keep clean. I wish the base were a little narrower to fit in my car cup holder. Still glad I bought it. I was intrigued by the premise of this mug. Like competitors, it isn't cheap. Normally I alternate between a Yeti and a Stanley. I expect my mug to fit in my car cup holder and keep my drink hot for at least an hour. This mug is larger and feels sturdier and heavier than my usual go-tos. I like the color choices and the bottom cover. The top is very ergonomic to the mouth, which is nice. I feel like the mouth shape is one of those things I will now expect on other mugs. The one disappointment is that opening and closing it makes a rather loud snapping noise. Thus, while I'd planned to take it to work and travel with it, I'll probably keep it at home since the noise could be rude in a work setting. It is easy to clean -- fewer parts and fewer places that can trap disgusting gunk. It keeps my drink hot, but I don't think that aspect is superior to other brands. Overall, I'm very pleased.

Purchased this to replace another brand. I’ve had it for a couple months and use daily. One of the main functions I liked the best is that the lid can easily be cleaned. I use cream in my coffee and the last mug had areas that were not easy to clean. I also like that it brings scalding hot coffee down a few degrees so you don’t burn your mouth. It does keep my coffee drinkable temp for at least 4 hours. Even in very cold Colorado winter temperatures. Mine does not leak and fits my vehicles cup holders. Unfortunately, the 16oz is too tall to fit under my Nepresso machine. I also wish it came in red. Otherwise, great coffee mug. Highly recommend.

I am a nerd for Ninja branded items so I was very excited to see a travel mug made by them. It works extremely well. Sometimes I forget how good it works and burn my mouth with my hot coffee many hours after I pour it into the mug. I also like it fits into my car’s cup holder. Even better, it is dishwasher safe.

I would have given 5 stars because it is the best coffee cup that I’ve ever used but for some reason it lost its seal. I am unable to use it safely because my coffee can now spill. I bought it jun 20, 2025 and the incident happened January 7th. I just received my new one because I like them but for $44 I am hoping it didn’t mess up on me again

This is expensive and it was a gift I am so glad I received. My husband bought himself and I one for work coffee. It’s so good at making hot coffee drinkable. Keeps drinks hot for a long time.

Excelente termo, conserva muy bien la bebida caliente

Keep my hot drink warm for 5-6 hrs

Love it great quality and sip makes it very easy to drink whilst in the car

Nice design and excellent quality

The item was faulty and leaks air with a chirping noise and does not keep drinks hot. How do I get a replacement.
