My Take
I adore this product and use it whenever I can. Its really fun for me to so easily visualize my students' growth with the data they provide, especially because typically grading these kinds of assignments can be so time consuming. I love the InqBlotter feature (real-time, specific information about students that are struggling, so we can provide specific, immediate, feedback). Its also pretty great that many of the labs they have are difficult to do in a real-life, classroom setting. Additionally, the labs that ARE replicable in a classroom can easily be used as an introduction to a hands-on, in-person lab.
How I Use It
I use Inq-ITS labs at the beginning and end of every course, and whenever there is a lab relevant to the content I am teaching. I often use it after the students have made progress in their understanding of the content, so they can make informed decisions in their labs. Occasionally I will actually use it as a hook or a way to evaluate prior understanding of material, but ONLY once they've had plenty of experience with Inq-ITS labs/ other true inquiry experiences.
