We have a lot of iPads in our K-2 grade levels and the headphone jacks are continually being broken off inside the port by students not handling the equipment properly.
We researched solutions and found iFixit's Grip Stick tool. We figured we'd try it out and as advertised it worked perfectly. Recovered 18 iPads that had been sitting in the broken pile for months.
This is a definite must-buy and must have in any IT tool kit.
