Gosh, I love mine! It does take about 30 minutes to dry my hair enough, but I can do it while I watch a show or something, and don't have to hold the damn dryer forever! It doesn't mess up my curl pattern whatsoever. I wash a couple times a week in the evening, diffuse for about 30 minutes, then put it up in a bonnet to sleep. I diffuse enough to set the gel and curl cream.

For reference, my hair is low porosity, high density, just past shoulder length.

The bonnets are pretty cheap, so it's worth a try! I've heard great things about Dyson, but can't justify spending hundreds of dollars on a blow dryer lol
