content: Because this is an Apple product, I didn't read the reviews carefully. Didn't expect serious problems.The big issue: Because I am right-handed like most people, the cord does not reach the plug on my MacBook Pro, unlike every other mouse I've used! No where did I notice this limitation in the Amazon product description. I work faster with a mouse than with the Pro's trackpad.Now that I've tried this mouse more than a month after receiving it, it's probably too late to send it back and probably too much of a nuisance.
