Our winner had the widest mouth in the lineup, which made it simple to fill—no spills or drips. The screw-on lid had a wide, arched handle that was easy to grip and turn, though users occasionally took an extra few seconds to get the lid on track. We liked that this model was dishwasher-safe and had no extra parts to remove during cleaning, and it survived three indoor drops despite its 2½-pound (filled) weight. It's also available in a 16-ounce size, if you prefer a lighter load.
