## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Good tumbler
  

*by T***F on Reviewed in the United States on 27 December 2023*

The tumbler is good size and sturdy.  The lid fits well but I am not a big fan of the mouth opening and the straw hole which has a plug on it that has to be opened for the liquid to flow out of the mouth opening.  But overall it is a quality tumbler and will keep liquid hot or cold.

### ⭐⭐⭐⭐⭐ 







  
  
    Good Quality
  

*by D***L on Reviewed in the United States on 10 December 2023*

Being an engineer I got this just because.  This came with two metal straws, one straight and one with a bend, and two rubber tips.  Also provided were two cleaning brushes, a twisted wire with nylon bristles good for cleaning the straws and a soft spongy thing with a plastic handle of questionable value and durability.  The lid has a drinking opening with a plastic snap closed cover.  There is also an attached rubber stopper for the drinking straw opening.  The entire lid closes very snugly making it a little difficult to remove.  This will probably ease a bit the more it is used.  The cup itself is stainless steel with a fairly thick black coating.  The vacuum cavity seems to be about the same thickness as other cups.The cup was left overnight full of water and a few ice cubes.  By mid morning the water was still cold but the ice had melted.  This fared as well as other cups I have used.Overall, I would say that this cup is as good as any other cups that are commercially available that I have tried.
