Overpriced, fragile, and unreliable....
Overpriced, fragile, and unreliable. Wish I could return it.

Solid scale. Feels sturdy and well built. The app however in true Acaia fashion is lackluster and poorly built. This scale is a pain in the butt to set up via the app and you can only connect it to the pearl scale if the phone app has not already occupied the connection to the pearl. Just get another standalone scale. Also the scale seems to go through the battery pretty quickly so maybe my issues will be addressed by firmware updates. Fingers crossed.
