## Customer Reviews

### ⭐⭐⭐ 







  
  
    Great for two mug sizes; super helpful mouth seal; has strong silicone smell
  

*by H***D on Reviewed in the United States on March 29, 2018*

I purchased this set of lids to avoid spills during the long walk back to my desk from the cafe at work (and to stop using paper cups and sleeves every single day). Having the small and medium sizes is great: the two larger sizes fit my 16 oz. Starbucks mug, while the two smaller sizes fit my standard 13oz mug. The lids do not leak while walking nor drinking, and the mouth seal is great for preventing spills, too. However, I can't get over the smell of the product. As I'm drinking my coffee, all I can smell is the silicone. For now, I've resorted to only using the silicone lids for transport back to my desk, then I remove it and drink from my mug without the lid. Hopefully the smell will fade after a few washes?

    Bad smell and taste!!
  

*by J***D on Reviewed in the United States on December 4, 2018*

I have had these for a few months now. I still cant drink out of them! I loved them when I first got them. They are different sizes so you can find one to fit most cups...but not my larger Starbucks ceramic mugs.The sad part it after washing them(as the instructions say), I made some coffee and then put this lid on. Then the coffee ended up tasting like plastic! It was horrible. So I figured I might have not washed them well enough. So I put the kids in the dish washer and then also soaked them in a vinegar bath and then boiled in hot water. All of these things will usually clean out any smell or taste they could leave behind. But No. They smell fine until they touch hot temperatures! As soon as hot anything touches it, the smell comes back and it leaves a funny plastic taste in my drink.

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent product!
  

*by K***. on Reviewed in the United States on June 6, 2017*

Fits mugs and reusable Starbucks cups. The leaf covering the mouthpiece is a nice product design. It keeps from splashing while walking or in car. Easy to clean. Cool colors. 3 sizes available that fits a variety of mugs and cups. Good for toddler cup training.
