It just not a way of thinking. Its the countless stories heard, first hand experience and knowing people with problems. I live about 25 miles from Vortex, there is plenty of market share in my area to hear a lot about it.
We are talking about Razor II scopes. Not Crossfires or Diamondbacks or even PSTs. That is the problem. People get a bad PSTor their buddy buys a crossfire for their .338 and it breaks and they say all Vortex sucks. Not true. They make a wide range of optics from $199 to $2500 and in this thread the OP is asking about Razor IIs. Not others in the line. Vague statements like above are doing nothing to help the OP with the question about Razor II scopes.
The Razor II scopes have proven themselves reliable and capable since they came out in PRS matches and other use. Have some failed? Yup. So have every other brand. NF makes great scopes also but again the question is is there a $1000 difference. And it's not all about "the means" either. I have the means and have used S&Bs, NF, USOs, Hensoldts etc in my years of competing and know about what optics bring to the table. If you think that your money is better spent at NF then get one. it's your money but it comes down more once in this price bracket to the features and reticles. I like the knobs and reticles better on the Razors. I like how they zero also. I moved from S&B 5-25s to the Razors for that reason. Glass was a push.
So OP take a look at them and see what you like and where your money is better spent. And remember when reading all this to look at people who have used the Razor IIs and not other in the Vortex line to get a direct comparison and opinion to help your decision.
