Does the Conair Infiniti Hair Designer dry your hair out? Does it work? Please Help!!!?

My hair is curly and I'm tired of using all my night getting out of the shower to blowdry my hair then straighten it( i straighten it at night because i don't have enough time in the morning) I'm thinking about getting the Conair Infiniti Hair Designer. Does it straighten your hair? Does it work quick? Does it dry your hair out? Am i better off using my straighten and blowdryer? Please help me!!
