I'm the only IT Analyst at my site and I have to be the hands to fix everything from software, account access, to hardware support. I also have to travel to other sites to help out and this tool kit goes with me every time. My kit mainly includes the pro kit, ratchet, magnetic mat, and, etc. My first repair job was taking 3 broken laptops and putting together one that works.
All the screws were easily removed with the pro kit set and the magnet mat was sheer brilliance to have with this repair job. I would highly recommend any IT Tech or hobbyist that has the inclination to rip apart electronics. The pro kit by far is the best kit for laptop repair out there.
The one thing I would love to see you guys make would be a custom tool bag for your tools. I have a small one from that huge anchor store at your local mall which works well, however having a custom IFIXIT bag made for their tools would ROCK!
