Not a fan. . .

[This review was collected as part of a promotion.] So I love the color, handle and straw, but the lid is not screw on so it doesn't feel secure, and it is just a bare metal bottom so it scrapes tables way too easily.

Just a little too big

[This review was collected as part of a promotion.] Looks great but just a bit too big. Often won’t fit under water dispenser nozzles and so I have to use a secondary cup to transfer water into this mug.

Great for hydrating

[This review was collected as part of a promotion.] I drink a lot of water throughout the day and this tumbler is great for volume and staying cold. The handle makes this large vessel easy to carry and grip and doesn’t get in the way in my car’s cup holders! The straw is comfortable to drink from and comes apart easily for cleaning.

[This review was collected as part of a promotion.] I love this tumbler. I especially love that every part is dishwasher safe, the color is not going to peel off, and it holds a ton. Best cup I've ever bought!

Works Great, Straw Comes Out Easily

[This review was collected as part of a promotion.] Love this cup. My only complaint is that it’s really easy to pull the straw out so my toddler is often soaking wet after getting some water. Other than that we’ve enjoyed it so much and it definitely meets expectations!
