What do you like best?
Nearpod is user friendly and I believe it is free depending on which edition you choose to use. I use the free Silver edition. You can create slides (similar to those in PowerPoint), import slides from a file that you've already created, add photos, and add audio. You can insert images or websites via hyperlinks. The best part is that you can also create quizzes and polls right in your presentation and the audience can respond via their phone, tablet, or lap top.
What do you dislike?
It can be time consuming to import slides that you've already created, and with anything, can take some time to get used to where all the tools are located. I haven't had too many formatting issues when importing slides from PowerPoint, but most of my slides are pretty basic. I'm not sure how animation (such as fly-ins) transfer into Nearpod.
Recommendations to others considering the product
Give it a try! It's definitely helpful if you include questions/polls into your current presentations to elicit audience feedback.
What business problems are you solving with the product? What benefits have you realized?
I use Nearpod to increase my use of technology in the classroom. I used to use two different formats for presentations and for quizzing/polling my class, toggling back and forth between the two platforms. I am now able to combine those two things (content and review questions or elicit feedback/participation along the way) very easily and increase participation in the classroom. These days, it is hard to get students to put their phones and tablets away, but if you incorporate them into their learning, it helps keep them engaged and decrease the urge to check their phones throughout class.
