Do I really need it?

I'm a FTM expecting my baby boy in July. I'm debating whether or not to put a bottle/breastmilk warmer on my registry. The one I am looking at is Kiinde Kozii breastmilk & Bottle Warmer. Does anyone else use the same one? If you use a warmer which do you recommend and why? Or do I even really NEED this kind of product?
