The art-Bella hair dryer is by far the best I've used. When it comes to blow drying my hair it can be a chore because of the length and thickness. Usually blow drying my hair takes me atleast 15-20 minutes, but with the art-Bella it took less than 10 minutes. It gets very hot and has a powerful blow. The diffuser works great I had ALOT of volume after using it. It did get very hott near the end and the extensions are very hot to the touch after use, I would let it cool down before putting it away. Over all this is a great hair dryer that does it's job.
