I don’t like deceptive advertising. I saw a commercial yesterday that showed someone dancing with a pet and it named a website and said to go there if you “love your pet!” Then there was a comment about giving away free dog treats for joining. Instead of coming right out and saying that they are a dog treat company, they beat around the bush by trying to make you think you’re going to a website devoted to pet lovers in a broad sense. I might seem uptight for being frustrated, but I don’t see why a business can’t be straightforward when presenting itself to potential customers. This is especially important for new customers. That’s because I’ve seen a lot of scammy companies take advantage of being vague as a means to deceive and con. For instance, don’t try to sell an herb mixture as a magical cure of coronavirus, we’ve heard that song and dance before. But one of the worst offenders that I’ve seen in recent years are the companies that make those miniature evaporative coolers that are branded as “AC” for “air cooler” or “air chiller” instead of air conditioner. Usually the advertisements brand these products as new inventions meant to revolutionize the heating and cooling industry, but ironically they utilize perhaps the oldest form of indoor cooling technology. Evaporative cooling happens when dry air passes over or through a wet medium and causes the moisture to vaporize. The temperature of the air lowers, which depends on the ambient humidity and the strength of the air current. But these tiny air coolers have fans so weak that they’re unlikely to have much of an effect on your air temperature at all.
