I ain't a big Vortex fan, but ####, a $200 Chinese red dot is a gamble no matter what name is on it. They (Vortex) are the #### for warranty, you would have the new replacement at your door with pre paid return for the broken one in a day... maybe 2 if you are rural lol.
Sig Sauer...the name is thrown around on a pile of stuff, GSG junk, Chinese red dots and scopes, use to be a name associated with high quality German ####, people would source out German P pistols over the US made, then they got kicked out of Germany in 2020 for being too American lol.
I do like the Sig USA made brass though, it's good ####.
