Playstation Laser lens replacing

Ciao to everybody!
I know it's a simple operation...but i did a Video tutorial about the lens replacing and i put its on youtube some minutes ago
The operations are for the "fat" playstation model (in the tutorial i've used a scph1002 model)
The playstation lens sometimes have problems...so maybe this tutorial could be of help (i hope )
