Contigo AUTOSEAL Stainless Mug, 20 oz

I love this bottle. I got the 24 ounce one so it holds a good deal, and the design of it makes it easy to hold and drink from. I have found that several of the bottles that hold larger amounts are too big around to fit comfortably in my hand, but not this one. It hold ice for a couple of days, and keeps drinks cold. I have not tried it with hot liquids yet. I find it really is spill proof, and I like the location of the button you push to release the liquid. The only thing that I would change about this bottle is to add a handle, either on the side or on the top that you could loop your finger through to make it easier to carry. I have not yet taken it in the car to see whether it fits into the cup holder, but just by looking at it, I think it will. One other thing I like about it is that even though it is slender, the bottom is not so tiny that it is top heavy. I have another bottle that I got that is so tall and the base is so small around that it is top heavy and falls over easily. Not this one. So in short, I would recommend this bottle , you won't be sorry for purchasing it.
