$400 Dyson Supersonic Blow Dryer: Overpriced or Innovative?

It feels like becoming a real adult when you make the first Dyson purchase since it has always been known as a fancy household appliance brand. In terms of price itself, Dyson products are usually double or sometimes triple the amounts you pay for regular ones. So, there is no surprise how crazy the price tag is when it launched the high-end hair dryer line, the Supersonic, in 2016. This time, the Dyson Supersonic Blow Dryer is labeled $399, roughly 56 times as expensive as the regular Revlon hair dryer ($7.03 from Walmart). Therefore, here comes the real and the most important question: is it worth it? Let’s take a look.
