To put things into perspective, here is the bug list of two manufacturers for two scopes that people seem trust implicitly without reserve.
Retail price for those 2 is easily 5x more..
I bold bugs directly pertaining to accuracy of data and basic functions of the scope...
Warning: lots of bugs, and serious ones... I hope people don't loose their trust... What do we do then?
FIRST:

(not that this manufacturers dishonestly calls them "Improvements" not defects
... At least first one is honestly admitting they are bugs (defects) and owns the obligation for fixing them.
