I fell for a scam of over pricing. I brought a lens after the guy showed me a very impressive demonstration. However like always when spending hundreds of dollars unexpected I felt uneasy about it, questioning myself if I did the right thing or not. So to put my mind at rest I did my Internet investigation and found out I over paid by $300. Then I can across consumer reviews on the location with the same complaint is have. This really hurt me , because I'm not a rich person and I really work hard for my family. How and why they still in business? I've found reports as far back as 2008. I hope this helps someone. It's a shame you have to do an investigation before doing business with anyone , but I'll do just that for now on.
