Very noisy, unreliable.
I had (2) of these models. When I had problems with the first one, I returned it for a replacement. When I had problems again, I returned it for a refund. The tray opened and closed slowly on both. I had intermitent problems with the drive reading data on a RW CD. I have two slower (8-4-32) HP drives that have worked flawlessly. They were both able to read the same data that the 9710 could not. I don't know if it is a flaw with this model, or I happened to get drives from a bad batch. Either way, with the problems I had, I could not count on the drives when I needed them!
