I hate some of the scammy “as seen on TV” products, because I had a few serious headaches in the early internet days before I could check multitudes of forums and social media websites for reviews prior to buying. I don’t know what annoyed me worse—the induction style soldering iron that never worked, or the copper-coated cookware that was stickier than my 30-year-old stainless steel fry pan. Both of these products were massive failures when I got my hands on one of each. I see a lot of those copper-coated fry pans at thrift stores because people buy them and then get rid of them for nothing. My sister had one that she threw away one year after failing to use it for cooking a side dish during a holiday meal. I have heard rumors that some of those copper pans were good, but that it was a quality control issue at the factory that resulted in the ones that were glorified paperweights, but I wouldn’t want to be the one to waste the time to find out for sure. I would much rather spend that time exposing the scam behind these products being sold as “personal air coolers” which are far worse. They’re underpowered evaporative coolers that are underpowered and given the wrong application altogether. You need a low humidity level for an evaporative cooler to work in the first place, in part because they rely on vaporizing water into a mist and adding it into ambient air to get the temperatures to drop. If the ambient air indoors or wherever you’ve got your “personal air cooler” stationed is too wet from the start, you’re not going to have evaporative cooling of any kind whatsoever.
