Great bottle for the price. Quality bottle. I like the chug drink tops. Less complicated and easier to clean than the straw configurations. This one is pretty simple with the cover as the leak-proof lid. It seems to work well, but you have to make sure it is locked down or it will leak or spill out water. I prefer it as a screw lid because you know that they are locked closed. Not sure on the long term whether the lid will hold up. The color is different than the pictures. It is solid gray color not the gray and stainless steel in the pictures. The gray and stainless looks better, but not a big deal on a $13 bottle.
