Which laser should I buy and how to change my ps2 laser?

For the PS2 Slim SCPH-79001''https://amzn.to/49lhhfA'', the correct and most commonly used replacement is the PVR-802W laser lens. This laser is fully compatible with the 79xxx series and is widely available online. Replacing it is not extremely difficult, but it does require opening the console and handling the ribbon cable carefully. Also, don’t forget to remove the anti-static solder blob on the new laser before installation, otherwise it won’t read discs. If you follow a guide or video tutorial, the replacement should be manageable even for a first-timer.
