I like my scales. They give me lots of information I find useful.
The research I did before buying directed me to a scale with multi point measurements, so as well as the foot sensors, mine has a hand bar, which is held as measurements are taken. This gives a more accurate (interpret accurate in your own way), and certainly, in my findings, very consistent readings. I have mine set to read in kg, and it reads to 0.1kg. I can step on and off repeatedly and always get the same readings, which is like. I've never been tempted to do all that standing on one leg, or standing at the front/back of the scale pad.
The fat and muscle readings are expressed as a percentage, and I like to keep an eye on those (the scale memory helps with the actual numbers) to ensure any weight loss or gain is fat or muscle respectively. Visceral fat is displayed on a linear score of 1 - 30, with the manual expressing the normal/abnormal bands for interpretation.
I like all the data, but I'm a data sort of person. Ahem. To be honest, I'm moderately unconcerned of a number says 3, 6, or 8, provided I am seeing the trend or steady state I am looking for, and I am within the bands I have set for myself.
I picked my scales up on eBay, new, at a great price. In August I have to decide if they travel back to UK with me, or whether I buy another set for the UK base. Currently, I think I'll have another set.
Mine are the Omron BF511.
