Anyone own a 1.5'; sedu hair iron?

I am interested in purchasing one but not sure which size to get, the 1'; or the 1.5';. I wanted to know if anyone owns a 1.5';, can you do curls on them and does it turn out nice? I know that the 1'; one you can but not so sure about the larger size.Anyone own a 1.5'; sedu hair iron?
The 1.5'; will straighten your hair faster than the 1';, but will not be as effictive in curling. If you want to curl, I suggest you get the 1';.Anyone own a 1.5'; sedu hair iron?
I have the 1.5. I have long hair so I got the bigger one and it straightens my hair super fast. It does great at flipping the ends but it doesn't curl quite as good as the 1 inch would. You basically just get loose waves.
