I have that exact one, and I've never been without a tool that I might need when it comes to computers. There also isn't really a tool I don't use on a regular basis when I'm working on my computer.
i don't know to be completely honest those tools look rather weak i work at a hardware store over here and i wouldn't give those tools the time of day if you haven't brought them already head to your local hardware store most of the time you can get most of the stuff you need for a cheaper price and higher quality
