Super! @hubbi | Watch Out!
Note: This is just ”my personal opinion”, not intended to “judge” the reviews you have made.
Pros:
The main advantage, of course we can use it to see any direction that we can not reach with the naked eye. At least, this is better than the mirror glass, because the range can be 360 degrees (can spin)
Cons:
In my opinion, this kind of product is not really needed by the general public.
