## Customer Reviews

### ⭐⭐⭐⭐ Efficient
*by M***. on 5 March 2025*

These tips prevent spilling very well however material quality is not very good.

### ⭐⭐⭐ Average
*by C***R on 22 April 2024*

I am not 100% happy with it but can’t really explain why. It just feels it doesn’t isolate although it seems to do it.

### ⭐ Look elsewhere
*by A***A on 12 February 2025*

The stopper is even too small for 30oz, it fits but once you push the straw through it carried the stopper along into the cup. Be warned
