Q: This charger is much sturdier than the mac version (which my cat chewed through in a matter of days). I'd read another review that said this adapter didn't work on the aluminum PowerBooks, but it works great for mine. In addition, the product arrived in about one day. I ordered it on a Friday morning and received it on Saturday before noon. I would highly reccomend this product.
A:
Positive
