Works quite well for me
I have very thick, naturally curly hair, so I was a bit doubtful about how well this straightener brush would work.  After using it about 5 times, I'm liking it more and more.  One pro is that it really cuts down on the time it takes me to do my hair.  This morning it took me less than 5 minutes to get presentable once my hair was dry, and that's a record!  I have noticed that the humidity makes a difference in the performance of the straightener.  When the humidity is high, it doesn't work quite as well for me, but remember that my hair is thick and curly.  Today, though, it worked very well.  It's great to use when I just want to quickly straighten and go, but I will still use my flat iron for the front & sides when I'm needing more of a finished look.  One con is the design -- the temperature control is on the handle and it's easy to accidentally change the setting.  However, I love that there's a display so I can readily see the temperature.  I had borrowed another brand from a friend to see if a brush would work on my hair, and it did not have a display.  In fact, I couldn't even see if the brush was on.  This Magnifeko brand, however, is great because of the display.
