I like that you can easily add new fields to your questionnaire at any time without having to redo all of it or change things around too much. It's easy enough so even non-technical people who are not comfortable with computer software will be able to use this tool effectively. There is nothing really wrong about dataskskill as far as functionality goes but there could definitely be some more options available within their dashboard such as adding custom questions/fields etc.. We have been using data skills since last year (for our client) and we've had no issues whatsoever!
