Now that I agree with. Unfortunately their usage in lower end products, and also the move to lighter weight products with higher torque due to brushless motors, seems to have reduced their usage. Maybe because they are an all-or-nothing failure point. Unless you really abuse the gear box, plastic gears don't tend to strip out all at once, they just get "worn" or "sloppy." That said, I think a lot of products are a race to the bottom in some regards.
