Hi J.! I have to use a hair straightener every day. I have naturally, thick wavy/curly hair that frizzes out. I've never used the CHI but my sister-in-law is a hairdresser and she has one. She's been lucky because hers has not had problems, but she says that many people in the industry have problems with it. She does not recommend it. So I found a great website (folica.com) where people can give reviews on different hair products. I ended up buying the Solia and it is currently priced at $88.00 with FREE shipping (comes with a free pouch that I use on my bathroom countertop, so it won't get damaged). Cheaper than the CHI. I've been very happy with it. I've had it since Christmas and it has not failed me yet. Very durable. I like the cool blue color. And heats up quick. I used to have a cheaper straightener I bought from Wal-Mart for $30. It took me forever to straighten my hair. This one has cut my styling time in half. Check out the link here & read what others are saying (many used to use the CHI):

They come in different sizes (3/4", 1", 1-1/4", and 1-3/4"). The prices will vary by a couple of dollars depending on what size you want. I have the 1" one. The link above is for the 1-1/4". It has the most reviews (over 2,500)... You can also search the site to look at other popular hair straighteners (or products). The Solia is one of the most popular ones since it's priced under $100 and does a great job, comparable to the CHI.
