There is definitely a learning curve for this product. The tracking sheets that came with the instruction manual were helpful, and I found the rest very informative. The results seemed accurate. I had high hopes for tracking my health gains, but after only 7 months, I wiped it with a damp sponge and the scale completely broke, all data was lost, and it stopped working. I felt overall I had been very careful with it, but it turns out it's very sensitive and you can't really clean it. I'm told they probably won't replace or fix it even though it is less than 1 year because I wiped some dust off it, and that I would probably need to buy another one. After spending what amounted to around $150 on a scale after taxes and shipping, needless to say, I'm a very disappointed buyer. I hoped for more customer support than 'don't bother sending it to repair or replace as (they) are not likely to do either.' I consider this a buyer beware situation. Know that you need to be exceptionally careful with this product if you purchase one. Other than that, I liked it.
