It's MUCH better than Google Translate and cheaper than Tally. I use it both for student tests and for company recruitment. The UI is still mediocre in places (e.g., previewing longer answers in the workbook—you have to download a PDF to read longer responses), but the developers are trying. A new version is now available, so it's great!

I highly recommend it—for both personal use (e.g., creating a survey for friends) and business use (recruitment, registration forms, tests, surveys, feedback).
