At the moment the question box only allows 150 characters. There is a workaround: to add text in a separate box, and only by hoovering does this additional text become visible.

There are 2 problems with this: (1) 150 characters is very limited for many question types. In my case, for example, I want to present a short clinical case, which is basically not possible with the current version of the Mentimeter. (2) The workaround does not work well (adding in another box that only becomes visible by hoovering). This workaround has poor layout and if you want to supply a PDF of your question set, most of the text is not visible.

Socrative allow for many more characters and as such I´m forced to choose Socrative. If Mentimeter didn´t have the 150 character limit I whould choose to use Mentimeter.
