One out of three isn't bad - for a baseball batting average but not for a health and fitness device
I looked at a number of smart scale comparisons on YouTube and other sources before selecting the Fitbit aria. Based on these materials I opted for the Aria because of accuracy, ease of setup and sync and its non slip legs. After receiving and and epic set up experience I can refute the easy set up. It's convoluted - the setup guide starts with downloading the app which then leads the user to the Fitbit website to do the set up. Problem is, you must join Fitbit on the app which is utterly unclear.  That's worth a good twenty minutes frustration. Once logged in the setup is pretty easy - other than the units dripping back to default a few times. My last disappointment was to step on the scale and having it do the scale equivalent of a wheelie.  I should have bought a Harley. The weight measurement seems accurate but the body fat %age is a trend line only.
