Collapsible Cup Travel -12oz Foldable Coffee Cups with Lid for Office,Travel,Camping and Hiking, Microwave and Dishwasher Safe-12oz

I bought this because it is similar to a cup sold in the UK (Pokito), which is not readily available yet in the U.S. Let me tell you this CLTEIN's mug pros and cons.Pros - It holds 12 oz. Yes, collapsible, easy to clean, easy to carry (both collapsed and when full of coffee). It does fit into the cup holder in my vehicle. I like that - collapsed - it fits easily in my backpack or suitcase.I don't use it every day, because I have a metal travel mug for that. I've used this one (CLTEIN) on a trip, where I knew I would want a travel mug at my destination. I've also used it a bit around town. Today - as I write this review - I'm using it, because I wanted to bring my remaining morning coffee with me to work and I knew that would fit nicely into this mug. I should keep this collapsible mug in my backpack, so it is available when I'm on the go.Cons - It does keep the coffee hot, but not as hot - I think - as my metal travel mug. That though is a minor con for me. A more major con is that the sleeve tends to fall down. It could be that I've just not yet gotten it up high enough on the cup. So when you put the cup down, it might slip off. The other con - again minor - is that the top does not have a vent, which means that when you take a sip, you can fell the sides of the cup move as the pressure in the mug changes.Overall, I would recommend this mug to other people and I would buy it again.BTW it is eye catching and I've had people ask about it!

My company, in order to go green, eliminated all of the paper cups. This forced me to find an alternative.I found this nice foldable mug. Doesn't leak if tipped over and is very stable when sitting on a table. The cup folds and unfolds with little effort.Con: I have detected a strange smell if a hot liquid is placed into the cup. The smell seems to be diminishing over time, so I hope its just temporary. This is the reason for 4 stars instead of 5 stars. The cup is supposed to be made out of a silicone approved for food.

I'm a grad student and bike to class every day so I was in search of something that wouldn't take up much room in my backpack. This little cup is great now that it is getting colder! I am able to put some tea bags inside when it is collapsed and heat it up when I want something warm. Plus it saves me a lot of money since I don't have to buy a cup each time I want some tea or coffee.It did have the strange smell that another reviewer noticed but that went away after I gave it a deep clean. The cup is strong but pliable so be a little cautious when you put the lid on so that you don't accidentally collapse the cup again. The only thing it is missing is a ventilation hole since it will suck in when you drink but that doesn't bother me. It did just fine in my dishwasher and in the microwave. I have washed and used it several times now with no breakdown or change in the structure.I have received a lot of compliments on my little cup and I love it! Highly recommend!

Its okay but needs getting used to. Folds up small and fairly lightweight. Negative part is that it collapses too easliy and squirts beverage out cap when it does.

This mug is great. I am one of those paper cup people -burning my hand and spilling! I am always grabbing one and now I don't worry because this cup fits in any bag. It is big enough for a regular sized cup of coffee! I will be buying more to use in the camper! No more risk of broken mugs! Coffee Travel Mug -CLTEIN Collapsible Certified BPA FREE Food-grade Silicone Coffee Cup Pocket-sized Camping Mug with Lid Reusable for Travel and Hiking,Dishwasher & Microwave Safe-12oz(Grey)

UPDATE: this cup hold smells like crazy. I cannot wash it enough and it smells like whatever I drank that day and stays until I drink something else with a strong smell.I enjoy this cup for coffee at work. It is easy to clean and compact to fit in my purse when im done with it. It handles hot coffee well. The only thing im not a fan of is that there is no vent hole when drinking, but its because the cup seals completely to avoid spilling, so its worth it :) also I just use a straw and its all good. I love this cup and will probably buy several in the future!

Got a set of two of these for my wife to take to/from work. She was bringing regular mugs back and forth once a week because water at the office is so bad that she can't even wash anything with it! These solved that problem. She swaps out one every day...we wash it... she takes it back and swaps... rinse/repeat! Everything is perfect, and they're sturdy when you have the plastic rings in place. Minor issue...since it's silicone, the tea odor doesn't fully come out. That would be true with any product made of silicone. But so far, no stains...just a mild odor of whatever was in there. They're a win for us.

As a frequent, and often international, traveler, this cup has served it's purpose well. It's lasted very well for 8 months of use now. Love that it's environmentally friendly (reusable), and collapses small. I wish it were a little larger, though. 1 2-16oz would be great. Also, like all things silicone, it will retain odors, which can impact the flavor of other beverages.
