Are there varying Specifications for Singer 7470 sewing machines?
Factory specifications are usually measured in laboratory environments paid for by the manufacturers themselves; therefore, the specifications are produced in an ideal environment unhampered by such inconveniences like “dust” and “needle-wear” and “humidity” and “the real world.” More dependable specs can usually be found on consumer-oriented publications like Consumer Reports. Another great place to find real-world specs is online reviews of consumers who have actually bought and used the product.
