Eline Smith, user from Cnet.com: It is really fast! I mean it is not only about its conversion speed, but also it's response to the latest technology. Well compatible with the Yosemite. Works great as usual.

Twisterella, user from Macupdate.com: For the record, M4VGear is a GREAT app which, for me, does everything it claims. It has a simply interface which is very easy to use. My only annoyance is the price: $49.95 is a little bit expensive, but intimately it does what it states and I'm very happy with the results.
