I am a one man computer repair shop. I got tired of using small metal screwdrivers to remove laptop keyboards. Especially after I put a scratch, although very small, on a customers laptop. I needed to replace a power jack and word of mouth is making my business grow so I thought it was about time to invest in a few items.
Between the Spudger and plastic opening tools the removal of the keyboard was a breeze and I didn't need to worry about scratching anything. I should have bought these when I first found ifixit.
I would say to anyone who works on laptops, whether someone else's or their own, buy some of these. You won't be sorry. I work mostly on desktops so far, but if I start getting more laptops, I'll be investing in more of these.
