FITBIT USERS: Question about the Aria Weightscale

Hello all! I own a Fitbit Flex band and use it religiously. I love it.

I was just wondering if the Aria(scale) is worth investing into as well. Like all fitbit devices it is quite pricey retailing at $129, but if all it does extra is record my body fat percentage why would one opt for this over the regular ones?

Right now I have a regular scale nothing too fancy, and looking at the body fat percentage ones at Target and the most expensive one is 79$ tops. I really love the fitbit and all but honestly, can someone tell me the reason one would pay the extra 50$?
