Poor in every sense.
The interface is so poorly designed that its unbelieveably user-unfriendly. Several suggestions: we want to be able to select and copy parts of the text, not the entire thing (go figure). With voice input, we want more solutions displayed (like with the typed one, where you get several meanings), not just one. Finally, the source and target texts should be able to be followed simultaneously, side-by-side, not one above the other (or at least not with all the scrolling).
