unfortunately just wasted $50 on this instructions say how to paid it. Device doesn't want too. Trouble shooting says to do it a certain way according to the response Device works so you can't log issue with them. Well scales turn on and charging works... but this product is unless for everything else. As it requires the product to Bluetooth and connect to your phone, needs the product to work for that. Even tried just pairing after a hard reset via settings on my phone without app and it still won't connect.
So buy your self a basic digital scale don't waste paying extra for this ones features like I did as it doesn't work.
