kat hat 3 I bought this for the purpose of opening the back cover of my mac to clean my fans. It helped me take the tiny screws out smoothly, and it even magnetizes the screws(weakly) which is a good point. When twisting it, you don't have to twist the whole screwdriver, you just need to hold its top and twist the other part of its body. What a detailed comfortability brought by this item.Will keep this with me for as long as my MacBook pro lives.
m 3 このロック機構のベルトを3本→2本→今回1本と買って3-4年使ってきましたが、かなり長持ちした最初の3本より2度目の2本はベルト裏目が柔らかくなってすぐバックルが外れ(で、最初のベルトを流用していた)、今回のものはベルトはだいぶマシ(でも5日で外れた)になったもののバックルが一週間で損壊。機巧は良いんだけどねぇ…もう現物見て買わないとダメかも?
