+ It works about as well as expected and nothing to complain about the basic design or user interface.
+ The resolution is high enough to not need the visible light camera image mixing. This is fortunate, because the visible light image has some lag and does a snail trail when panning.

- Initially I had one or two startup- hiccups and it even reverted to Chinese once. These problems went away once I fully charged the battery. But it hints to flaky power management or a bad/missing cap somewhere.
- It seems to be held together with screws, but the screws are hidden below glued rubber inserts. So will be tricky to swap out the battery when eventually needed.

Here is a span of 10 C:
And with a different palette:
