NinjaTravel Mug, Sip Perfect 16oz, Brings Hot Drinks to Sippable Temperature in Minutes, Stainless Steel, Leak Proof, Dishwasher Safe, Metal Insulated Tumbler, Onyx Black, DW1603BK

I purchased this product for my husband. He would always have to reheat his coffee throughout the day. And also had a tendency for spilling. This container solved both problems.With the lid closed you can drop it from the roof and it won’t spill! It’s heavy duty and well made.The best part is that the coffee stays hot for 10 hours! Yes…10 hours.

I was skeptical. All I wanted was a purple leak proof hot drink bottle for my coffee and tea. I enjoy my hot drink to be hot! I cannot stand lukewarm drink that’s supposed to be drank hot. I also don’t want to burn my tongue so finding that perfect temp is a trick. The first time I used it, I made my loose leaf tea with boiling water, filtered out the leaves and poured it into this bottle. I let it sit for 3 minutes with lid on. Then it is drinkable! I’m shocked. This is more efficient cooling than letting my tea in a cup without lid for 10+ minutes. And it seems to stay in the same temp. I’m sold! And also, if you like purple things, the purple bottle is so cute in person! The only bummer is they’ve increased the price by 30%! I bought it when it was $34.

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.

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.

Im disappointed with the cups design. I wish the lock and unlock feature was on the side of the lid instead of it being on top. As a result I tend to forget to "lock it" when I put it back in my gym bag and ive had multiple occasions where it has spilled and ruined its contents.

Cools hot drink to drinkable temperature within minutes and then slowly releases the heat back to keep the drink warm for longer. I have had this mug for a few months now and am always shocked that the last drop is as warm as the first drop.If you want to use it as a thermos and keep it warmer for longer, just pre heat the mug with hot water before putting in your beverage. That will heat up the wax insulation without "cooling " your drink.My father and brother have had these for over a year and love others too.

The media could not be loaded. Best ever travel cup. Would definitely recommend!!I recently purchased my Ninja Sip Perfect Travel Mug 16oz.I made my hot coffee at 14:15pm. I took my last sip at 18:00pm and it was still hot and fresh like it was just made.I love it. Easy to use. Very stylish, fits nicely in my car holder with or without silicone sleeve bottom. No issues of leaking. Easy to clean. Longer lasting quality is worth my pennies.
