I believe that the con that it has limited imaging filtering to be correct and the rating should be upgraded.

I like it for quick, simple-but-beautiful presentations.

I've seen my share of student presentations that are copied and pasted from wikipedia and students basically face the screen and read the slides as if for the first time. Haiku Deck only allows minimal content so the student presentation takes the focus and not the supplemental PowerPoint. Haiku Deck is a great alternative to PowerPoint.

I like this product for its simplicity, elegance, and usefulness. It supports teaching students to create presentations that foster extemporaneous explanation instead of reading from the slides. It exports beautifully to various social media sites and is easy to send in an email. I would like to see a little more with how to use the features of the tool box.
