I could be having too much fun with this BUT this kit has many of the critical things. MacGyver could make a spaceship with this stuff - which makes it a perfect gift for an Engineer or Maker. Add in a soldering iron and the sky is the limit. Honestly, just one of these would probably not be enough. You might need two or three. One for home. One for your desk at work. One for your normal work station. I have a six piece plier set that I keep in a similar case that I don't keep on the magnet bar - just so they're not magnetized. See? One is not enough.
