It takes up counter/kitchen space, and if you leave rice in it too long, it go bad and disgusting (so don't do that). It makes rice, and for me, I cook chicken and vegetables in it, just put it on top of the rice, for single pot meals. It comes down to how often you eat rice. It makes it way easier, since you set it and forget it (just don't forget too long).
Importantly though, they've had decades to refine the design, so the cheap one from Walmart does just fine, no need to buy a $100 Japanese one if you're exploring if you even want a rice cooker.
