Customer Reviews:
I have the Fitbit Aria scale which I’ve had the odd issue with and even had to have it exchanged once when it died. What I loved about that scale was that it would track your weight and BMI every time you use it which was great to look back on. I almost bought another one for my 2nd home but couldn’t justify the $180 cost for a scale. I then found this one but was hesitant to try it as I like having wifi where I don’t need to worry about having my phone etc but gave itt a try. This scale is the best! It’s way smaller than the Fitbit one and much nicer looking and it takes the measurements much faster. You just need to have the app open on your phone but it connects immediately every time, no pairing or anything needed. It shows WAY more than you get with the fitbit and then actually gives you feedback on the results, like bone density etc. The best part is that it syncs with Fitbit and with Google Fit, so now I can use my existing Aria scale at my one home if I want and then use this one also and still have the measurements all in the same place. Definitely pleased with it, especially with the fact I could buy almost 4 of them for the price of one fitbit!!!
