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

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.

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.

Love how sturdy this is! Great quality and drinking from it is actually refreshing! It doesnt leak at all! However, it doesnt keep my drink hot for very long. I make my coffee at 630am every morning, and with my Caribou travel mug, my drink is nice and hot until about 1pm before it starts to cool off. With this cup, my drink is already cooling off around 10am. I Love the cup though so ill keep using it, but it does need better insulation for hot drinks.

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.

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.

Keep coffee, nice and hot. I add MCT oil in my prior thermos that oily on the outside. The ninja thermos does not leak the oil out.

Can't find a replacement lid. The little rubber bit that seals the lid came off while washing and fell down the drain. NINJA support won't replace the lid or missing parts. Suggested buying another poorly designed mug.

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.
