The BlenderBottle Radian Insulated Stainless Steel 26 oz. Water Bottle is a great option for anyone looking for a durable and insulated water bottle. The bottle is made of high-quality stainless steel, which makes it extremely durable and resistant to rust and corrosion. The insulation keeps drinks cold for hours, even in hot weather conditions. The bottle also features a convenient carry handle, making it easy to take on the go.

I have been using this Blender bottle for awhile now. This is excellent for my smoothies that I bring to work. I make my smoothies around 6am and drink half of it at around 9am and have the rest by 12 noon and it is still cold and there’s still ice shaved in it. It’s just the right size for what I needed. I bought 3 of this already for presents, and the recipients were happy to have.

It's a great water bottle to make odd protein and pre-workout combinations. Surprisingly, I have less trouble blender-ing with this smaller bottle than the larger ones, making me force down a lot fewer protein chunks. I haven't had it leak for real, however, if it's closed a little loose, I've noticed that some water will pool in the lid thread and it will spill all over you the next time you open it (this does not happen often and is user-error). One thing to note, as with all other water bottles, make sure to clean around the lip for mold/old crust AND inside the cap's o-ring.

I love this bottle. I use it everyday for my mixture of collagen and protein. Then I use it through the day for my water and crystal light. It keeps my drink cold and mixes it very well.

The build feels solid and durable, and the twist-off cap makes it easy to chug shakes fast. That said, the steel material can be noisy in crowded spaces, and it’s not completely leakproof. Overall, good quality if you don’t mind those trade-offs.
