Early Christmas Gift

Well it wasn't suppose to be early, but it was accidentally sent in my name and I opened it. My Love bought me a Babyliss Pro Ceramic Curling Iron. While I never use a curling iron I'm debating on keeping it or replacing it with a flat iron. I kinda said I would keep it and use it to straighten my hair. My beautician uses a curling iron to straighten my hair b/c I don't really like wearing it straight. I have to have my ends bumped. It makes my hair look like it has more volume. Keeping the curling iron will also help me reduce the amount of heat I use on my head. What are your thoughts?
