I have a launch PS2 and other than it making clicking noises, it still,works great. I also have a 50001 model and it's working superbly. They,don't get used daily so that might be why my launch one is still,working. ,
I got one when the first came out, but last month it stoped reading disks (it stoped reading CD's a long time ago) i was able to get it to work for a little bit so that i could trade it in for a slim PS2 ($80 trade in). it work out anyway because i was about to buy the network adapter anyway (still sucked).
