My partner was trying to fix a portable device the other day, he informed me that he knew what he was doing as he'd seen a tutorial video on Youtube. Well what he hadn't realised was that the screws holding it together had a weird slot on the screw-heads and he didn't have a screwdriver to fit it. I came across this precision screwdriver set which seemed to have everything he'd ever need as this has 98 screwdriver bits of varying sizes and slot designs.
This set comes in a plastic case and comes with other tools to help to take devices apart and I am happy to say that my partner loves this set and now has been able to fix his device. To see this Gocheer 115 In 1 Precision Screwdriver Set on Amazon use this link -
