Review on 5pcs Precision MacBook Repair Tool Kit: P5 Pentalobe Screwdriver, T5 Torx, PH000 Phillips Screwdriver, Ultra-Thin Steel and Nylon Spudgers - for MacBook Pro & MacBook Air with Retina Display by Dave Neal

Bought to open the Yoga C930 Laptop (4K screen model) as it uses a P5 screw to upgrade the Wifi card to Wifi 6 (aka AX) to update. Worked, very happy. I was careful to slow down, didn't rush to drop it or overtighten it. I'm glad it came with a spudger to remove the back of the device. Just make sure you orient the screws properly when you add them back. It also has a magnetic tip that makes it easy to pick up and remove. UPDATE: 11/29/2019 Works great, had no problem re-loosening the screws and using again. When the block is flat, hover over it and move counterclockwise to open and clockwise to close. It doesn't require much effort, but you press lightly. I think some accidentally use the wrong screw. The T5 and P5 are color coded, but make sure you know the type of screw on your laptop and use a little force when you push the tool down and turn it the first time. You can then sit down and undress as usual.
