Query: Disappointed

For years I've been using a 1/2" brush curling iron that works great. Recently they changed the bristles which use to be flexible and now they are hard plastic. They no longer grabs the hair and curl. So I've been looking for a new curling iron. I was disappointed to find this curling iron is made of the same hard plastic. These hard bristles do not grab the hair. I wish people who make these products would use them before they sell them. Anyone who would use a 1/2" curling iron would most like have short hair. Try grabbing a hold of your hair with this hard bristle curling iron. Not worth the purchase in my opinion.
