Contigo Stainless Steel Travel Mug

I have been purchasing these to-go cups since 2012. They are hands down the best design I have ever used, and I've tried a lot of different brands, including the very expensive Yeti's, but these beat them all. Yes, they are a little harder to keep clean, but if you keep on top of it like I do, it's actually pretty easy. I simply remove the cap and open the sealing mechanism, spray some dishwashing liquid int the cap and then spray the hottest water I can get from my kitchen faucet while holding the button down to clean it out. Then I toss it into the dishwasher with the mechanism open and it comes out clean every time. The key is to not let it sit with sugar coffee in it overnight or for long periods of time. I bought a brand new very expensive pickup truck in 2012. I was getting ready to leave for work early in the morning and set the coffee mug on my center console. When I took off down the road, the mug went flying into the back on the floor, and of course my first thought was 'Oh' XXXX' I just ruined my new truck's carpet. I immediately pulled over and then reached back to grab the cup thinking the worst. To my happy surprise, not one drop had spilled from the cup, so these have been my Go-To coffee mug ever since and will continue to be unless their quality really goes to hell. I do like my Yeti's and RTIC's for cold drinks at home, but for a hot coffee travel mug these are the best hands down.
