There are some products on the market that bill themselves as premium updates 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 plus then flip it to show the pan’s capabilities. But then the manufactured pans had a lower quality-control put into them plus more than 2 people like myself and others were disappointed when they couldn’t outperform our ceramic coated cooking ware. I suppose the few people who were lucky enough to get nice pans were glad, however they were outnumbered by others who bought 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 legitimately believed the SEO hype around some portable models plus manufacturers, you’d suppose that they are these wonder machines that outperform window s with much easier installation plus service. Unluckyly, portable s create new problems that do not even exist in the first place with tried-and-tploy window HVAC units. Window cooling system units plus split-style HVAC systems place their warm 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 cooling system units have a compressor inside the machine plus your home, which creates heat while cooling some of your air. To offset the heat, some of the frigid air is recycled to cool the compressor plus it’s blasted outdoors as waste.
