Yes, the lid requires some attention to clean and reassemble, but the mug is wonderful and has not leaked. I take it as my second cup on early morning volleyball weekends because I can fill it and throw it in my backpack without leaks. When I need my second round a few hours later, coffee is hot and waiting for me. Game changer!
I wanted a larger coffee cup, so I didn't have to refill it when I went to work. It holds more coffee than my other other coffee cup and it keeps it warm longer. Love this coffee bottle with the flex sip.
I wanted a hot beverage container I could safely throw into my tote bag, and not worry about spills or drips. So far this is it! I like the loop top handle. I recommend filling the container with hot tapwater before adding coffee or tea, it will keep your liquid warm for a longer time. It’s too pricey to buy at full price; I waited for a sale. Also, this company has GREAT customer service and product guarantee.
I have to agree about another review regarding the lid. I loved the idea of having a durable coffee mug that would keep the coffee hot but the lid ruined this cup for me. The lid is so hard to clean. In theory it seems like a good idea to have all the pieces come apart so you can wash every inch but if you don't put it together just right, it will leak. I've tried several times and I've stopped using this cup because of the lid. It very much "soaks" in that coffee taste so I can't really use it for other drinks. I'm thinking of perhaps purchasing a different type of non-sip, regular screw on lid if they make one just to salvage this purchase. It's that much of a hassle :(
