I love the sleek design of this tumbler and that it comes with two options of either a flip lid or a straw lid. I am a big iced coffee drinker even in the winter so I love being able to have the option of using the straw lid for that. My drink stayed ice cold all day. The tumbler isn't dishwasher safe (as is the case for most stainless steel tumblers) but it's easy to clean and I did throw the lids in the dishwasher with no issue.
