It is like any serious business deal. You are the designated "purchasing agent" for your "company." You supply the parts for your "company's" operation. But also, you are technically tuned to avoid substandard parts just because they are cheap.
My initial evaluation of Hiflow Filtro products was they are IDENTICAL to Kymco filters, Genuine Buddy filters and probably supply to Kymco. I have used them in every scoot that required a filter or cartridge since 2009 and have had zero problems.
