### ⭐⭐⭐⭐⭐ 







  
  
    Quality

They get the job done

### ⭐ 







  
  
    Ummm…no
  

*by J***N on Reviewed in the United States on 4 January 2024*

2 of the straw caps are a smaller size and don’t fit the straw.  The center cap that goes inside the Stanley doesn’t stay on so doesn’t prevent water from coming out.

### ⭐⭐ 







  
  
    Cloud didn't fit,
  

*by L***D on Reviewed in the United States on 11 March 2024*

Everything was perfect but what l really wanted was not fitting on my straw.
