I started testing essentially the following yesterday:

Overall, it's been nice so far.
Some points to note:
-If the Max 2 is placed in landscape mode, it can be held up by the stand portion of the keyboard, but it seems a bit precarious
-The touchpad portion is a bit on the slow side, but on a different device it wasn't so sluggish, so may be a future update to the firmware might help?
-The right button for the touchpad seems to act as a back button -- seemed odd at first, but more convenient perhaps than holding Fn down and pressing another key
-Long-pressing works via the left button for the touchpad so with a bit of patience, selecting text can be more accurate than using one's finger (well...at least my finger

)
