So many appraisals for a bad application

There is a timetable scheduling software called as Mimosa. It is totally unusable. There are lots of buttons in each screen that are totally not understandable by their labels. The labels have spelling errors. The graphical layout is totally unorganized. I think the users must have taken lots of training to be able to do something useful.

But this software is sold to more than 50 countries around the world. The user comments are very appealing. Let me show some of them:

"Thank you very much for your help, the software is excellent for our needs."
--- A.H.S., México D.F., Mexico

"I have tried the software and have experienced thousand easy steps and all possibility options have been fulfilled. Thanks."
--- E.G., Dehradun, India

"Mimosa is flexible and user-friendly. It makes creative timetabling possible at an affordable price."
--- R.M., Gaborone, Botswana

How might this be true? This is totally incredible for me. It is nearly impossible to use this software. How did so many people like it?
