[This review was collected as part of a promotion.] The perfect pair of Stainless Steel Tumblers. These are not only super easy to use and optimized with their straw technology, but they keep my drink cold or hot far longer than most other Tumblers. As long as the straw is closed leaks will never be a problem. Overall, my new favorite drink holder.

[This review was collected as part of a promotion.] I got the charcoal and cream colors, and they are beautiful neutral colored tumblers! I really like the retractable straw feature which prevents dust or bugs from getting into the straw. It’s a little on the heavier side but the handle makes it easy to carry. It does keep my water cold so I have no complaints! The slim bottom also fits inside my car’s cupholders.

[This review was collected as part of a promotion.] These tumblers are made sturdy and durable. Bring 30 oz, they hold quite a bit. It has a comfortable grip, is spill proof and the retractable straw is very convenient and on the plus side, protecting it from germs. It's very simple and easy to clean. It is stainless steel and well insulated, keeping your drink cold for quite a while. It fits in most cup holders also.

[This review was collected as part of a promotion.] Thank you for allowing me to try these out! These cups are amazing! Keeps my drinks cold literally alllll day! Very durable, easy to use, I can hide the straw to keep it safe from outside elements, very portable, light, and easy to carry and take on the go with me! Cleaning my cups is super easy as well! Great color choices too!

[This review was collected as part of a promotion.] This is my new favorite water bottle! I love the size, not quite as bulky as a 40oz bottle. It also fits perfectly into the cup holder of my car. My two favorite features are the handle and the retractable straw. I actually like that the exposed part of the straw is plastic and the straw extension in the cup is silicon. I feel like the end of the straw you drink from is more durable. And, I like being able to throw it in my backpack when it's closed and know it's not going to leak. I prefer a handle design that allows you to carry it from the top, instead of holding it from the side, so this is great. It makes it easier to carry when my hands are full. The cream and black are great neutrals! It's fairly easy to clean since the straw component comes apart. I live in the desert, so insulation is a hit or miss sometimes. But this one seems to do a decent job of keeping my water cold/cool, even if left in the car for a little while.

[This review was collected as part of a promotion.] LOVE LOVE LOVE. I absolutely love this tumbler. I love the color options and I love that it has a retractable straw. My drinks stay cold and didnt experience any leaking ir spilling. I would recommend thus bottle over any if tbe current top trending bottles. The straw design alone makes it above them all!!

Great tumblers with handles to carry. Easy to use. Easy to clean. Wish they had a skid silicone bottom so you don't make loud sounds.

I really love the water bottle. The lid broke on the straw mechanism. Is there any way to purchase a replacement lid for them?
