I love Dvorak and I love duets. This is perfect! You have to be willing to put in a little work (as does your duet partner), but the results are worth it! (I personally enjoy Op 46 better than Op 72 [these are the two opuses in this edition] because it tends to be more upbeat and feel more festive, but they are both full of beautiful music.)
As for the edition, the music is clear to read (if a little on the small side). The big issue with this is simply that it does not lay flat easily, despite the label calling it a lay-flat binding. Then again, what books that aren't spiral bound do actually lay flat?
There are a couple of places that I would have appreciated a little more editorial guidance, particularly for pedaling issues. But part of the fun is figuring those things out as an ensemble.
