I needed tools for all of my devices as well as others that I repair an maintain. I own multiple Macs, and PCs. Since Apple uses different screws I wanted to get a set of tools that would include those as well.
I also often find myself repairing things on unsafe or unfriendly surfaces, thus I needed a medium sized anti-static mat. I also loose tiny screws often... Again, instant solution was the magnetic project mat.
I used the tools for the first time to open my MacBook Pro 15" Retina to blow out dust and to tighten the screws on the bottom. I loved the toolkit, it has everything I need, all in a small footprint.
Purchase the Pro Tech Toolkit, it has everything. Quality of the tools is very good as well. I'd recommend to any other IT guru or repair shop/help-desk.
