Great concept, but body fat in accurate and not precise
I am a fitness junky, and I purchased this device because I already had a Fitbit and thought it'd be nice to have my weight and body fat automatically tracked along with my other stats.  I have been mainly disappointed with the product.  The body fat measurement definitely lacks accuracy and precision.  I wasn't as disappointed about the lack of accuracy (as mostly I was caring about a general trend) however the day to day jumps have been 2-3% at times.  That is much more than any noise in measurement, and is big enough to really hide your progress (or lack of).  I still use it because it is nice to track my weight, but probably not worth the high price tag.  I have attached a months log of body fat to show how big the spread is.  Swings of 3-4% are just unacceptable.
