Missed the mark

The straw does leak and I can only get a successful drink if the "breather notch" is in perfect alignment with the "breather hole". I shouldn't have to make sure, everytime I am thirsty and in need of a drink that I must first perfectly align those two things. I drive for a living and need a jug or mug that I can rely on. The straw turns so easily that I never know. Displeased.

Disappointed
on June 15, 2026
Posted by: Veronica D.
[This review was collected as part of a promotion.] My ice melts too fast in this tumbler and only lasts about 4 hours vs my Ella lasts all day long. I do like the soft straw but the inside of the tip of it stains easily from my flavored grape water but it does clean easily with my straw brush cleaner.

Hydration Sensation

[This review was collected as part of a promotion.] The tumbler is perfect for summer. I fill it with ice and water in the morning. After drinking the first cup, I can refill it 3 times before the ice completely melts. This allows me to have ice water all day. I love this tumbler!!

Not blue

[This review was collected as part of a promotion.] Love this cup as I have one in a different color. I was super bummed that the color is nowhere near a glitter blue… it’s white. Looking at the return process it just sounds like a headache so I guess I’ll just keep it and gift it to someone.

[This review was collected as part of a promotion.] I actually bought 4 , used 2 in the house and planned in gifting the other 2, who ever will get them I am very sure will be extremely happy getting that gift. A very well rounded product keeps the drinks cold.
