Worth it

My husband drinks more water when I make it ultra convenient for him and this helps accomplish that. Wish we had bought a 2nd straw, will wait until the next sale I guess!

The lid fits well, but the straw part is terrible. Due to the **** in the base of the 20-oz camp cup, the straw needs to be cut very short. Which makes getting all of the liquid impossible. The hole either needs to be to one or supply a flexible/curved straw. Just poor execution.

Great But Not Versatile

I love the concept of a leak proof straw lid. However, once the straw part is cut to the cup size, it's really only meant for that cup size. My suggestions would be to make the entire straw from collapsible silicone OR include a second customizable straw that can be cut for a different size. This would be good for those who have multiple MiiR cups in different heights.

Wonderful addition

This is great for using your cup as a straw cup ! So glad I purchased plus it doesn’t spill!

Use it all the time. Very glad I added it to my tumbler. And it was awesome to see a cutting guide on the package.
