There are some products on the market that bill themselves as premium replaces to older technology, however then fall short of their promises.
Copper coated cooking ware is one example that comes to mind.
I saw those commercials where the announcer claimed they were capable of total-nonstick cooking at medium to high heat with no oil or butter. They’d literally pan-fry a slice of cheese & then flip it to show the pan’s capabilities. But then the manufactured pans had a lower quality-control put into them & many people like myself and others were disappointed when they couldn’t outperform our ceramic coated cooking ware. I assume the few people who were lucky enough to get nice pans were cheerful, however they were outnumbered by others who purchased defective products. It’s smart to remember that something isn’t better simply because it touts itself as an improvement upon its predecessors. If you honestly believed the marketing hype around some portable air conditioner models & manufacturers, you’d think that they are these wonder machines that outperform window air conditioners with much easier installation & service. Unfortunately, portable air conditioners create new issues that do not even exist in the first place with tried-and-tplot window HVAC units. Window a/c units & split-style HVAC systems place their tepid compressors outside of the home. With the former the compressor is right outside the window, in the latter it’s in a metal enclosure outside. Portable a/c units have a compressor inside the equipment & your home, which creates heat while cooling some of your air. To offset the heat, some of the cold air is recycled to cool the compressor & it’s blasted outdoors as waste.
