This is a hair dryer made in 2017. The airflow and heat output are both fine, and it works well. I disassembled it because it stopped producing hot air, and I replaced the bimetal thermal switch. When disassembling it, the parts were stuck together and I had to pry them open, so there are small scratches on some parts of the main body, but this does not affect its operation at all. You can use it comfortably. I usually use a different hair dryer, and I kept this one as a spare for a long time, but I bought a newer hair dryer, so I have no use for this one anymore, and I'm putting it up for sale.
