Another way to understand the quality of a product is to understand from where the company sources its materials. All US based companies, other than Insensation, are sourcing materials from China, Russia, Belarus, Hungary and other authoritarian countries.
Insensation imports 100% of its product from Europe, specifically Greece, Germany, Italy, Netherlands and Switzerland

Other companies in New York, New Jersey, Florida and California have imports which have nothing to do with the marketing they promote.

Do your own research to find out exactly what you are buying.
