I am an IT technician and work mainly on laptops/desktop computers. In the pictures of the item description there is a clear pictures of someone working on the internals of a laptop. Albeit I work mainly on Dell鈥檚 the Phillips bits don鈥檛 fit the screws properly(not the correct bit), I am unsure of the proper size at this moment but I will now have to try and source this 鈥減recision鈥 bit size in the Phillips size I need. Just an oversight I believe but ultimately is a drawback for myself.
