I bought a Superdrive to complement the new I-Mac. It looked good and felt solid compared with other makes. Although its cable is ridiculously short and it will not work with a powered USB3 hub, I can live with that. However, the big disappointment is that it produced audio CDs in a format not recognised by Hi-Fi CD players (I did set the burn option to "cd audio"). I took it to my local Apple Store who could not not test it as they don't have HI-Fi equipment. However, rather than send it away to be tested, they quite happily exchanged it for a new one. Three months later, after burning some 30 CDs, it is working fine.
Perhaps I was just unlucky the first time but, on a value for money basis, I cannot give more than three stars. Whilst having trouble with the first one, I borrowed a Samsung. It is very flimsy but it worked perfectly and, at less than half the price, it has to be a better buy.
