$330 per year in savings sounds a bit low to me. I can save that much (or more) just with car repairs or maintenance. Even basic household stuff will typically cost $50-100 just for "the guy" to show up.
Pretty much do not have people show up and a whole lot can be ordered.
I personally didn't dare to try to repair my washing machine or dishwashers (beyond cleaning clogged pipes), although I know people who do.
The point of the right to repair bills is that the useful life of products can be extended through repair. So I guess some people who are always buying new replacements and upgrades would be less likely to need those repairs as many repairs happen later in a product's life.
I've fixed my washer and dryer before. Even just simple things like replacing the belts or resetting the thermal OL switch can be done by anyone, no qualification needed.
