Title: Cracks Easily - Cheap Plastic
Review: I use these in the classroom and after two uses the plastic cracks. I like to change the color of the water every so often but after taking the piece off a second or third time you're lucky if you get it back on in one piece. It's a waste a money, but I haven't seen any others.
