I purchased this a few months ago. It has the easiest setup and works great with the Apple Health app and Fitbit. I use it every day to track my weight loss goals. Hope this helps.
In case anyone is investigating scales, and are considering getting a scale from Weight Gurus (Greater Goods) with the expectation of consistent delivery of data from their app to Fitbit, you might want to be aware that there is a claim of integration, but its actual operability has proven to be weak at best in my experience. Further, the Weight Gurus folks have shown very little willingness to investigate the problem in any depth, which has certainly been disappointing. Buyer beware.
