40oz Stanley Crystal Crush

I already own several Stanley cups, so I'm a huge fan of the brand and the quality. The cup itself is amazing, as always — durable, keeps my drinks cold for hours, and the design is perfect. This time I ordered the light pink/salmon color, and even though it's beautiful, I realized it's very similar to a pink Stanley I already have. That's completely on me and not a reflection of the product at all. The color is still gorgeous — I just should've picked something different for my collection. I'm definitely planning to buy another Stanley soon, probably in a fun neon yellow or neon green shade! Highly recommend the cup — just make sure you choose a color that adds variety if you're a collector like me!

The Stanley tumbler offers a time-saving solution by eliminating the need for multiple plastic bottles. The ability to consume an adequate volume of liquids is crucial for maintaining optimal health.

I absolutely love my Stanley! It keeps my drinks hot for hours and cold drinks stay ice-cold all day. The quality feels very durable and well-made. It doesn't leak, and the design is both stylish and practical. Perfect for busy days, road trips, or everyday use. Definitely worth the price — highly recommend!

I love the cups due to when they fit in my car holders they keep my drinks cold for up to 24 hours just the right size love the color and the new design of the straw

I really enjoy the color and quality of this cup keeps my ice all day even pouring fresh water in it throughout the day which is nice. The water I refill it with is cool but still I work outdoors all day and usually my truck is either off or idling with no a/c running so it gets hot inside. Very durable I have actually dropped o. Off my tool box on my bucket truck and it was scratched but unbroken

Sometimes the lid gets stuck, like, horrifically so and I have to get my dad to undo it—and I'm not a twig, like I've never had to get him to undo a lid before, so this is not user error I promise. Just don't seal it tight and there won't be any problem 😃 And also if you don't put an absurd amount of ice in it, it'll melt quickly. BUT OVERALL, she's great, the color is beautiful, she's my pride and joy.

Disappointed that this cup isn't holding ice long. Example maybe 45 minutes. And that we cannot order another lid with a folding straw to match the cup.

Love the cup—I've ordered several and really enjoy the style. One thing I've noticed, though, is that this particular cup doesn't come in its own protective packaging and arrives loose in the box. Because of that, I've received cups with a worn spot on the handle showing discoloration that won't wash off, making it appear used, and the straw has arrived slightly bent. With better packaging, this would be a perfect product.

I purchased a Stanley 40oz tumbler with high expectations, based on the brand's reputation for superior insulation and performance. Unfortunately, my experience has been far from satisfactory. The primary issue lies in the product's inability to maintain ice retention—ice consistently melts within two hours of filling, even under normal indoor conditions. Given that this item is marketed for its long-lasting thermal retention capabilities, I find the performance to be significantly below advertised standards. This is not what I anticipated from a premium-priced, widely endorsed product. I have followed all usage guidelines, including proper pre-chilling, yet the results remain the same. Regrettably, I cannot recommend this item based on my experience, and I would urge potential buyers to consider alternative brands that offer more reliable insulation performance.

The cup does not keep ice. Constantly leaking from the top. I am switching to a different brand.
