Title: Works, But Forget About Listening To Music
Review: The deal with this is, yes, it will work and yes it is cheaper than buying Apple's overpriced replacement, however, if you plan on listening to any music with your laptop while plugged into this adapter you can forget it. Through laptop speakers it is fine, but through headphones or external speakers it will generate a very annoying hum due to the fact that it is not a grounded power supply (it has a 2 prong plug rather than three). I record music and found it nearly impossible, as it would pick up the hum from the adapter. And because my battery is nearly depleted, I could only record for a few minutes at a time, recharge and then repeat. If you are thinking about this product, I would just rip up a $20 bill or buy a grounded, Apple authorized replacement.
