Question: Your other product like this sold as a single has a lot of bad reviews on the lid.How is this lid different in design that makes it easier to clean?
Document: I love my Contigo containers. I put my whey protein shakes in them every morning and they NEVER leak. I wish cleaning the tops out was a little easier, but this model has a flip up apparatus in the lid that makes it a lot easier to clean than the earlier models of this product.Bottom line, I love them. They keep items both hot or cold. I put a bunch more on my bridal registry as well.
I bought this product in the past and loved it except for the lid which I could never quite clean properly. I ordered this as a gift and was very pleasantly surprised the see the redesigned lid that makes cleaning so much easier. It keeps warm beverages warm and cold beverages cold exactly as advertised. NEVER LEAKS!! It's perfect. Thanks Contigo for redesigning the lid! I plan to order new mugs for myself very soon.
I had been watching these travel mugs for a while and reading reviews. There was a lot of complaints about not being able to clean the lids properly. When I saw these with the easy clean lids I knew it was time to try them. So far I am very happy with my mugs. The lids are a breeze to clean and my coffee stays at the right temperature when I bring it to work. I am very satisfied with my purchase.
I love Contigo for its ability to keep my tea and coffee warm. But previous model was giving me hard life. New Easy Clean Lid is way better and easier to clean. Would definitely recommend it to anyone.
I've used the old style for over a year and never once had it leak, even after dropping it on concrete a few times. The new lid is really nice and much easier to clean. I bought mine directly through Contigo and I will definitely continue using their products in the future.
Like other reviews have stated these mugs do what they say. It keeps your hot drinks hot and cold drinks cold and do not leak. I love it and got two to give one as a gift. Highly recommend.
Did I say I love these. Keeps my coffee hot until it is gone. Also cold drinks it keeps them really cold. I gave these as a gift and everyone I gave them to loves them also. They couldn't stop talking about them. There is also one with a bigger push button on it and I don't like them as much. Easier to hit the button and spill. These are great.
Definitely dislike it a lot. This corporation claims that this product automatically closes and opens, automatically means there is no need to use for fingers.
Well worth the money. Strongly recommend this product...it keeps my coffee warm all day and my soft drinks and ice last a lot longer.
It did not keep the product hot for more than 2 hours.I like the cap as it does seal the coffee in and not drip.
Answer: The inside of the lid is hard to clean. So, I put mine in the dishwasher. Eliminated the problem. Hubby loves the cup.
