Review: Great toddler cup - Perfect training cup for my 2 year old. I wanted a simple no frills metal sippy cup and this was perfect for what I needed. The spout is adjustable so that helps when they are learning motor skills with tilting the cup. It’s pretty good with not spilling if it’s dropped but it will leak if it falls on the spout side but I don’t mind. It surprisingly also keeps drinks cold for a while Great budget cup. ## Features - 【Safe&Durability】Come on! Protect from disposable cups.
