Better than a scale & a measuring tape, not as user friendly as bioimpedence scales. Meant for professionals.
I was initially very excited to get this product after reading about it in 4 Hour Body by Tim Ferriss.<br /><br />However after using it for about 8 months, I've noticed that it suffers from the same potential flaws as calipers & bioimpedance scales. If you don't use the proper amount of gel, hold it at the same angle as last time, move at the proper speed, at the same exact location, then you might get a wild variance of readings.<br /><br />In fact the algorithm takes this into account and you have to take a minimum of 3 readings at each site, and then it averages the 3 readings ... if the ranges have too much variance, you will be required to take 2 more readings. I often have to take more than 3 readings.<br /><br />What this does that no other device will do is actually show you the size and amount of muscle over time on a given body part... although you really need to know how to read the ultrasonic scan to tell.<br /><br />I think this is meant moreso for professionals who have training in this field. I got this for personal use to get more accurate readings than my Omron or Fitbit Aria ... and while I DO get more accurate readings than those devices, I'm not sure if it's worth the price because I lack the training to effectively use it :\<br /><br />I must say the support you get with this is TOP NOTCH. The creator is a very smart guy. The software that this runs on is a bit out dated though, and the technology (USB) could be updated.
