I returned this item that same day it arrived. After launching the required software for the first time, I got a pop-up error message that said "software is not compatible with Intel-based Macs." This is a major incompatibility for for a huge percentage of mac owners, and it was not mentioned anywhere in the Amazon product info or specification. Furthermore, when I went to the manufacturer's website (Griffin Technology), I discovered that the product had been discontinued. Also not mentioned by Amazon.
