Hey Tracy,
Thanks so much for the review, really is appreciated by us here at SHO!
I'm so pleased to hear that your son is getting on well with his new Straw Lid!
Hope you have an awesome day :)
Best wishes,
Ellie
“Nice straw, really glad it's finally available in 1L size. I've knocked a star off because the sip spout tends to move slightly back towards closed position no matter how I drink from it, and that affects the effectiveness of the spout. But still worth it.”
