Seriously, how does anyone learn surface modeling at a professional level?

About 10 years ago I learned that China has 25 different ratings for quality. As some people say: You get what you pay for. Depending on the price and material requirements, many factories from many countries (including those in EU and USA) could offer you products either with top quality, a reasonable quality, or utterly bad quality.

Consumer electronics that feature shiny plastic (or CNC-milled) body need to fall under the Class-A requirement, otherwise the reflections would immediately expose any lack of good continuity or uneven areas. Even simple shapes for NURBS modeling such like hairdryers often have G2 continuity between the body and the handle, because most of them are shiny. Many power tools also have G2 continuity, despite having a matte finish.
Most of the sports glasses, and the major part of the body of phones, tablets, laptops are also G2.

The body of the Xbox One controller is G2 and that gives it a more premium look. However, the PlayStation 4 controller (Dual shock 4) has G1 everywhere and that alone makes it look of very low quality.
