Should you buy a Thousand Oaks Optical filter sheet from “Rix Beauty” (or any other non-approved vendor) at Amazon? For now, my advice is no. Why? Several reasons. The most important is you have no idea if the filter sheet was actually made by Thousand Oaks Optical, or if it is a fake. This also applies to all the other eclipse products at Amazon that are sold by non-approved vendors.
