### ⭐⭐⭐⭐⭐ CMOS for PS2 Slim
*by J***K on September 23, 2025*

Perfect fit! Installed on a PS2 Slim model 75001. Will definitely buy from again

### ⭐⭐⭐⭐ Wire is a little short
*by J***E on April 27, 2021*

Description says it's compatible with my computer, and it was, but the wire is a little too short to stretch across to where it needs to be placed on the laptop. Wasn't a fan of the pull it made on the wire when it was plugged in, so I ordered another one with a longer wire.
