I want to start an appliance company that offers 10 year warranties with an additional 5 year replaceable parts availability promise. The designs will be simple, functionality simple with minimal quality of life improvements, and all repair manuals will be published on the website along with tutorial videos, while also banking on building a product that simply lasts longer.

I’m willing to bet that if that is what you advertise on, the longevity of the product at a minimal price, then the company should do fine.

Everyone always talks about speed queens and I always have to chime in. The cost isn’t worth it. As shitty and consumerist as it sounds, it has been far cheaper to replace every few years than buy a speed queen. For one SQ washer I could buy 3 of my Samsung washers, and for one SQ dryer I could buy 4 of my Samsung ones. I got both my washer and dryer used. The washer was bad within the first year and replaced with a near new referb and it has been good for 5 years. The dryer is still working After the 6 years I have had it. They cost me a fraction of the SQ price even with the extra washer purchase and still work. Even if they both broke every other year and got replaced, my 10 year cost is still less than buying a SQ. The price just isn’t worth it.

It shouldn’t. Older mags with poor tolerances and poorly designed followers used to have this issue and that is where people got into the habit of saying/doing/teaching that. Newer mags with better openings and followers no longer have this issue. This is true for both the AR and the AK platforms, the two most popular platforms in the world.
