This is the first professional-grade blow dryer I've ever purchased (saving up my points really helped!) and I'm not disappointed. This thing could blow my ears off my head! ;)
The power and heat are really phenomenal, and I've been able to practice my blow drying technique with great results.
The one drawback: the buttons/switches are not my favorite. There are two issues - 1) the positioning is such that I accidentally hit them all the time, and 2) the order of the switches is not intuitive - I have to keep looking at it to adjust the intensity or heat level.
This also came with a Sedu mini straightener, which also has a poorly positioned switch - I kept accidentally turning it off mid-use!
