New Conair Infiniti blowdryer in the house

So I saw this Conair Infiniti blowdryer at Marshall's and thought it would be very fantastic if it worked like they said, but I didn't get it as I was leary of using it, unsure if it was made for 4B hair.  I came home and researced it online.  I found it on Amazon http://www.amazon.com/Conair-Infiniti-Tourmaline-Hair-Designer/dp/B000FFI228/ref=cm_cr_pr_product_top & it has over 180 reviews, mostly positive.  There are reviews from African Americans who had success, so I really want to try it, since I have some difficulty with blowdrying my hair.  It was $30 at Marshalls, but I saw it at Big Lots for $19 so I purchased it there instead.  Review coming next!!
