Has anyone used zyBooks in their classes? I've seen some good comments on the SIGCSE list about them. I would primarily use this in our CS I class (Java) with their lab feature as a way to provide students with review and practice problems.
Currently, our CS I course only consists of 3 weekly 50-minute sessions, we have no assigned textbook (and much to my dismay, so separate lab sessions for students to practice the material - which in my opinion severely limits their uptake/comprehension of this material). I'm hoping this book/approach may be at least a partial remedy.

It looks promising, but I would like some feedback from those who have used these (even if in other than Java courses)

To be a bit more specific (as suggested, +1), I'm curious about the students' reaction to the text and the labs. I.e., did they like the text, found the explanations clear, the lab/exercises helpful for learning and reviewing the material.
I'm also interested if the instructors found a greater understanding of the material by the students who used the labs.
