The batteries do not discharge as sometimes noted in the comments for this product.
I'm not against not satisfied with the connection with my Iphone or recognizing that it does not remain stable. As soon as the balance is turned off or when I leave the room with my iPhone I have to relaunch the entire procedure which is a bit boring in the end.
perhaps a WIFI connection would be more stable but poor reception where I use this scales.
Overall satisfied with the accuracy, the design and the product in general but certain lack for connectivity which is the main selling point of this product at this price !!
