New View Gifts 30oz Tumbler Mug with Lid and Straw, Reusable Insulated Mug with Handle, Stainless Steel Tumbler for Iced & Hot Beverages, Green

I mix up a thick, frozen smoothie every morning, pour it into an insulated Simple Modern tumbler, and take it to work with me. Occasionally, though, I have accidentally left it at work at the end of the day and been without a tumbler the next morning. So I decided to go shopping for a “back up" tumbler and found this one. All in all, this is a great buy, as it's a pretty nice tumbler. However, where it fails is the lid. The tumbler itself is nicely insulated, I like the color, and it comes with a thick straw. But the lid is not nearly as insulated as the rest of it, and when you screw it on, it leaves the straw hole in an awkward spot. That's not to say that I regret my purchase, especially since this one is just my "back up" tumbler. When I need it, it comes in very handy. But the poor insulation of the lid means it will never be a favorite, and I will always rely on my nicer Simple Modern tumbler.

The lids do not "fit" the mugs. they were not engineered to do so. they fit randomly onto the mugs. yes, I have purchased several. they don't get better.
