Doesn't live up to the hype

I got this for Christmas last year and it's great but doesn't keep ice as well as expected... Bottom dents very easily. Lid is hard to clean and get into the nooks and crannies but the tumbler itself is nice
I would recommend this to a friend!

I really like my Stanley IceFlow flip bottle. It keeps my water cold for hours, even when I leave it in the car or take it to work. The flip straw is super convenient and doesn’t leak, which makes it easy to drink from throughout the day. The bottle is sturdy, easy to carry, and the size is perfect for staying hydrated. Definitely a great quality bottle that’s worth it if you want something durable that keeps drinks ice cold. Highly recommend!

Build and Portability
The sturdy build is exactly what you would expect from the Stanley brand. It feels solid and well-constructed, capable of withstanding drops and bumps without compromising its integrity. Despite the large 40 oz capacity, it is remarkably easy to carry thanks to the integrated folding handle. It’s also easy to use—the flip straw allows for quick, one-handed sipping without needing to tilt the bottle, which is perfect for driving or working out.

Maintenance: "Easy to Clean"
A common issue with many reusable bottles is the difficulty of cleaning the straw and lid. However, this tumbler is easy to clean as well. The lid is designed to be disassembled easily, and the materials are dishwasher-safe, ensuring that you can keep it hygienic with minimal effort.

The vacuum insulation performs flawlessly, keeping drinks cold for hours on end. The flip-leak-resistant straw is a standout feature, providing a secure seal when closed so you can toss it in a bag without worrying about spills.
