“Love this. It's not totally spill proof, but I understood that before ordering and don't need a vacuum seal for our purposes. The sip opening is a great size for smoothies. My young kids can easily manage taking the lids off (to scoop out oatmeal, for ex.) or tightening them up while having a drink. We haven't needed the straws much, but they work pretty well with the lid and seem WAY safer than hard reusable options like stainless steel, so I'm glad we have them.”
“These are great for preventing spills. I do have a sensory child and he tore the lid on accident. This is no fault of the product as my son is very rough with things and loves to push things beyond their limits. He was very upset that he broke his lid though because he loves them too.”
