The straw width and silicone straw could be wider
"I’m a huge PlanetBox mom—it’s the only brand I use for all of my son’s lunch and snack needs. He also uses the kids’ version of this water bottle. I absolutely love the concept of this bottle, especially that it’s plastic-free and made with safe materials. My only issue is that I find I have to suck quite a bit harder to get water out compared to something like a Stanley. I think if the steel/silicone straw were slightly wider, it would make it much easier to drink water quickly. That said, this could totally be a personal preference or an issue that doesn’t affect everyone else!"
