This is a great product. I have long, thick, wavy, frizzy hair and it takes me about 30 mins to style my hair with this and it looks great. I got lots of compliments after my first use. The only reason I give it 4 stars (I would give a 4.5 if a could) is because it is bulkier and heavier than other ones I've used. Not a problem for me to use at home, but this isn't a styling tool I would travel with.
The edge is bigger than what I expected; however, it worked well for my coily hair type. It was easy to straighten my hair in less than 30 minutes. The one thing that I did not like is that is is hard to clean after the use.
Love the consistent heat settings… the cord can be fairly cumbersome, but other than that I love this product! My only suggestion would be to provide a travel sleeve and a tool for cleaning.
