SUNWILLInsulated Coffee Mug with Lid, Travel Tumbler with Handle, 14oz Stainless Steel Cup for Camping, Office, Home, Powder Coated Navy Blue

I tell you what, THIS has got to be the BEST cup you'll ever own. you don't need to spend big bucks to get the best.. this keeps my coffee hot for HOURS and hours and my cold drinks cold FOREVER- it's just amazing I just ordered another one..

First order arrived without a lid, but was sent a new mug with lid within four days which was excellentI have a similar mug by a well known brand and this is as good for a fraction of the cost

Attractive, sturdy, capacious insulated cup with plastic lid that has a slider to reduce spillage.The plastic lid also helps prevent lip-burn on metal when drinks are hot.Cup has Excellent insulation so hot drinks keep good warmth for a couple of hours or more!A spoonful of baking soda in the metal cup left to stand for a couple of hours will remove tea and coffee stains. Don’t put your cup in the dishwasher lest the ceramic paint might flake off.I have two such cups and use them constantly and with Satisfaction !

As you can see from the first picture, I wanted to test a few different styles of Yeti and against a cheap substitute. (This Sunwill, the Sursip and BJPKPK are ramblers) I wanted to supersize my morning coffee & choose this 14 oz Yeti mug. Yes, it does take 14oz of coffee with room to fit the lid on it. The Yeti is superior in build quality than the Sunwill. But ergonomically, I like the size of the 10oz Yeti. Instead of gaining the extra 4oz from height, Yeti gained it in width, as in 100% of the 4oz. This made the cup unwieldy and awkward to transport, and I was uncomfortable lifting it in front of my laptop. The handle of the 10oz Yeti fits the fingers better than the Sunwill, (wider and more material used) making transport from coffee pot or room to room more comfortable. As for the temperature test. Once again, all the Yetis are superior. But how much is what matters. For the first hour the heat retention is identical (nearly), and then after that who cares if the Yeti keeps it hotter longer? It is already too low temp for coffee. As for the lids? IF you want a tight no leak fit. Get a YETi!For me, the 14oz model is just unwieldy. Some people are Oakley ~ Nike people and some people DGAF about brand image. I decided to pay half as much and keep the Sunwill as I DGAF. Just my Joepinion. For me, close enough is the same. Obviously, you are a different person with different wants and needs, and I hope I gave you the ability to make a wise choice for yourself.

The Yeti is superior in build quality and ergonomics. It is more comfortable and fits the hand better (mine anyway). From the pictures you can see that the Yeti can be used with a straw or sans lid. Not so with the Sursip. I barely use a straw and the Sursip came with two as it came with two lids. My dad has the Yeti and was crushed when he lost his straw and found that Yeti makes getting a replacement cost prohibitive. As for the straw itself, the Yeti is larger and better in every way. My dad also had to buy a cleaning wire for his Yeti. The Sursip comes with one. As for the temperature test. Once again, all the Yetis are superior. But how much is what matters. For the first few hours they are nearly identical, and then after that the Yeti is again far superior at keeping liquids colder for longer. But, if you left them both out with liquid and ice overnight, they both will still have cold liquid in ice come morning. As for the lids? IF you want a tight no leak fit.

Really pleased with this cup! Lid stays on well, keeps coffee hot, easy to wash in the dishwasher. I bought two and they have both been great for several months so far.

I love my cup holder my tea. And keeps it hot. I love the color

Great for workKeeps my coffee and tea hot for hours

I was hoping it was spill proof. I searched on "adult sippy cup". The first thing I did was fill it with water and hold it upside down over the sink. I almost poured out.I might search a replacement lid. The body of the cup itself is nice and sturdy. It holds the right amount. The blue is nice.
