Bests & Worsts Reviews from Amazon

The straw ones require a little finesse. If you microwave with the straw in it makes a fountain (fun!) If you insert the straw without covering the opening with your thumb it shoots liquid out like a rocket (more fun!) They're fine as long as you don't do those two things. Unless you like making milk fountains. But who's going to clean that shit up? You are. That's what you get for having kids. Now go put yourself in timeout and don't forget to bring the mommy juice.
