In my case, nothing was technically broken. I just wanted (needed, really) a better PC Toolkit. I recently purchased a SAS Expander for my Windows Home Server and needed to install some HDDs into the SAS Expander, plus miscellaneous other maintenance and upgrades.
Everything went smoothly. I have only installed one HDD so far. Need to buy some new ones before installing any more. I was slightly disappointed that the Screw Driver and Bit (#1 Phillips) didn't seem to have a magnetic tip. The Bit itself (and extension pieces) are magnetically held in place, but it did not pick up the screws magnetically.
