Carter Move Mug with 360º Sip Lid

Bought this several months ago, when I had to buy the sliding lid separately, and it was only available in black. I don't like using it, because the lid's inner workings are so convoluted, it's almost impossible to clean without running under hot water for much too long. It's just a sliding lid. So I decided I would try the 360 lid, but it releases a flow so wide it spills around my mouth, unless I very carefully and slowly tip the mug... not what I want to deal with in the truck at traffic lights. Plus, I put hot coffee in it almost two hours ago, and the outside of the mug at the bottom is a good 10-15 degrees warmer than the top. It's a beautiful looking design, cosmetically, but has too many functional flaws to be a practical coffee delivery system. I'm now shopping elsewhere for a travel mug.
