The o-rings are perfect for CD/DVD tray drive belts. The square format fits the grooves perfectly. Being as they come in 100 PC packs, they should last at least until holograms take the place of mechanical drives!

These were a good price and there is nothing wrong with them. They are just o-rings though so there isn't much to say about them. I found no defects in any of them though so I guess that is as good as it needs to be.

What can one say about o-rings. If you order the right size and it is sent to you, they will fit.
Well, these fit.
