Once it's setup it's great!
Wanted to give this 5 stars because i do love it. But, wifi setup was a bit of a pain. After 20-30mins of tinkering i did manage to get it working. The other down side is that it will occasionally mistake a guest if they are similar in weight. If you add them as a user, then you need to tell it which one is which each time (which defeats the total simplicity of the device). So once you're beyond that, it's zero thought. Wake up, stumble on scale, walk away. No buttons, no thought and your data shows up on the website. They also have an API and ways to pull down your data. Although, I wish they had a built in csv import to import old data you may already have.<br /><br />8/2014 update:<br />It's very picky about the wifi. It's occasionally lost it and had to go through the painful setup again. But, i'm not sure i would lower to 3 stars... because it still works great and I still love having the automated data. I think i've replaced the batteries (4 AA) once in the last year.
