Been using these scales for several weeks now. I'm blown away by how good this product is for the money. Takes only a minute or two to download the app and setup an account. Turned on the device and it instantly connected via bluetooth. Too easy! Gives you an amazing amount of data. Allows you to set goals then see trends in your data. And when my son got on it, it detected it was a different person and asked me which account I wanted to associate the data too. 100% recommend this product.
