Brush iron vs. curling iron
The brush iron seems not to be hot enough.  It takes a long time to heat up fully and once heated requires considerable time in each place to curl the hair.  I have to work with it more.  It could be that I'm expecting it to be more like the curling iron I have, and it is unquestionably slower to heat and to do the job I want to do.
