Just zeroed both this evening.
red dot, actually responds to turns of the screws with less sensitivity. The knock off moved with the slightest touch of the adjustment screw which meant you would get it zeroed and then when the lock screws were tightened it moved
much brighter with a new battery, I’d guess almost twice as bright to my eyes than the knock off
my red dot is the click adjust and I prefer it to the rheostat type on the knock off and my cheap version doesn’t actually fully turn off
the glass is better/ clearer
the scope is much clearer glass than the 1-8 vortex it replaced which is a bonus as I actually changed it because of the reticle plus the quick adjust locking caps are handy.
better light gathering plus it’s a true 1x
