   I’m not buying another one of these, this is TWICE the seal has broken, making it unsanitary to drink from. Threw it away after this picture. DON’T WASTE YOUR MONEY!!! Those droplets aren’t on the outside of the cup but BETWEEN the layers of plastic. I’m DONE with NINJAS!

   I got one of these tumblers with my Ninja coffee bar a few years ago, and it was my favorite cup. I used it all the time, but it got damaged. I searched until I got a new one and I am so happy. I use it with cold drinks and for my water at bedtime. It’s still cold in the a.m. Great cup!

   I put all of my hot and cold drinks in this and it works perfectly! It keeps the drinks well insulated and you can see through the cup, which makes it feel fancier. There are lines on the cups that help you measure out your ingredients. They are dishwasher safe (top rack only), which really should be the only way you wash them- except maybe with a dish TOWEL. I washed a cup with one of those dish wands that’s supposed to be non-scratch and it completely scratched up the beautiful finish of the cup. My girlfriend was mad about that and I have my own cup now. But it still is a great cup. The only other downfall is that the opening in the top where the straw inserts is not splash proof, but my girlfriend doesn’t seem to have any problems not spilling it.

   I have the coffee machine and I had to have the cup. It great quality and it fits my Nina ja machine. I tried hot and cold coffee in it and it’s perfect. The double insulation and lid are awsome. I am so happy. I am making so many different drinks. Can’t wait to see what else I can make and take with me.

   Unfortunately, my ninja coffee maker is not able to fit any other tumbler, and I lost the original, so I had to buy this one. It’s pretty expensive, but I bought it because I make iced coffee frequently. Not amazing at keeping the coffee cold, though.

   Love this tumbler for my iced coffee every morning, and my ice water throughout the day! Perfect size, easy to hold, my baby can’t pull the straw out which is a plus. Doesn’t condensate!

   Like a billion other people I was sucked into the Ninja Coffee Bar infomercial and I have to say I really love it but found a problem as soon as I attempted to make iced coffee: my Starbucks cold cup wouldn’t fit under the NCB. Guess that’s a good way to sell their cups though. This fits perfectly under the coffee maker. The lid is angled so if you want to drink out of it without the straw you can. I haven’t tried it that way though. Thick plastic straw is included and has the ridge on one end to keep it from falling out of the cup. Double walled so it shouldn’t get drippy condensation on the outside. I can’t say for sure how well it keeps drinks cold because I am an iced coffee guzzler, but I would imagine that it works as well as any other cold cup. This fits in my trucks cup holders. The reason I take one star away is the opening that the straw fits through is not a circle but rather slightly elongated to allow you to drink without the straw, but the opening was just big enough to allow a fly to get in my drink 🙁 The cup also has lines on it that are used if you are following a drink recipe and need certain measurements of different ingredients- nice for people who want their drinks tasting the same each time. If the straw opening was round so stupid coffee loving flys couldn’t get it I’d give it five stars.

   I received on with my ninja coffee maker. This is the only cup I used. It kept hot things hot and cold things cold. I ordered two more to keep in my collection. Wonderful! EXCEPT now that I had it awhile, these cups do stain to the point that you cannot remove the stains. I reserved the two additional cups that I purchased for drinking water only.
