Expert Reviews


What reviewers liked

It’s also not really that expensive – both sizes are under $30. When you take into consideration the quality of build and performance of this bottle, this easily becomes the best value for money you can get.
But if you’re not into the straw, reviewers also note there’s another open-spout cap. “I love that I have the option,” explains one customer who calls this water bottle a “serious value.” She also adds that it’s completely durable, because she’s dropped it a couple times on a cement floor and “it has survived every fall.”

What reviewers didn't like

One issue is the size variety; this bottle is only available in 24oz and 40oz.
