After doing iPads for years, I and our teachers have actually come to prefer just a solid plastic or rubber case with no funky buttons or handles. Found the “special” case rubber just becomes loose, home button distorted, and the screen covers more trouble than they’re worth. Been doing this for 10+ years, and haven’t had a single iPad break with a case like this (not necessarily this model, but it’s the style we get. and this is with grades PreK-2)
