I received Fluke Toner as a gift because I passed my Journeymans test and I needed a case to protect it and it was exactly what I wanted . Case. Additional molds for 2 spare 9V batteries are great if your toner dies in the field. I use a grid with pockets to store extra test patch cords, a number book, and a precision (thin) screwdriver. fantastic purchase and if you have this fluke toner it is an absolute must have.
