Pretty great

It does what Smart Converter Pro can’t due wrt. translating audio from any .mkv file to .mp4 - much appreciated!
One feature it doesn’t have, unlike SCP, is that when file is converted it does not automatically deliver it to iTunes. Eliminating the extra step would give it another star. The conversion does win points for being super fast, which makes it almost okay not to have the auto-delivery.
