Poor battery life.
I purchased this earlier this year, as I really wanted a small cordless straightener for travel.  It never seemed to charge all the way (no directions to see what the display should look like), but I still liked it.  Now it barely holds a charge for 10 minutes, after being plugged in for 6 hours.  Very disappointing…time to get a new one, but not this brand.
