I LOVE THIS BOTTLE! No more thirsty business trips 💧

I've been coveting a Memobottle for years and I finally splashed out (pardon the pun) and bought one. I love how good it feels in your hands, how easy it is to slip into my travel bag, and being stainless steel - how easy it is to clean,

I'm SO GLAD I bought one. Definitely a 10-out-of-10 purchase. 🎉
