Dyson's official website focuses on customer group descriptions such as age hair, length and, user preference.
Amazon focuses on product segmentation such as different hair dryer color in the same hair dryer model, paying attention to user preferences, and verified buyer and not verified buyer customer reviews have inconsistent reviews. Both reviews need to be differentiated.
Facebook is a social networking site. User review theme is the gift giving and receiving process. They focus on the logistics experience of the purchase.
In conclusion, here is the recommendation on how to read the reviews online: Use official website product to read how to use the product. Use Amazon.com to read product specifications. Use Facebook to see product logistics.
