I purchased the tools to use at my volunteer "job". Our group of GE retirees gifted more than 650 donated computers last year. All computers and other equipment are given to any qualified non-profit organization that requests one or many computers. Read about our group and the process for requesting computers at computerrehab.org. The 54 piece Driver Kit is a second kit that I own. Although there are duplicate bits in the two kits, there are many bits in the second kit that are not included in the original kit.
Most of our repairs are successful, having the right tool makes the access and disassembly much easier. Our failures and obsolete equipment end up being stripped and recycled. We raise several thousand dollars a year from recycled copper, aluminum, motherboards, CPU's and memory boards. Most of the dollars are used to purchase hard drives, printer cartridges, batteries and tools.
Any repair job is much easier when the right tool is available. i believe that one should buy the best quality tool that is affordable.
