Contigo Auto Seal West Loop 1.1 Travel Mug, 20 oz, Matte Black
This a review for the Contigo Auto Seal Travel Mug. You see right here the way it works, it's pretty simple. The button in the back where if you push, it opens up this mouth hole. There is locking mechanism where if you lock it, and then push the button, nothing happens. Works pretty well. I've had it for about six weeks now. Never spill a drop. As you can hear, lots of liquid, no spillage happening. It also holds temperature pretty well with your hot drinks stay hot, and your cold drinks stay cold. Twenty dollars, I'd say this is steal, and my only worry is that eventually, this top is no longer going to work. About twenty dollars, you can buy one every six months, and still wouldn't break the bank. So five stars.
