This pedometer is very easy to program (weight, length of stride, time) and use. It is precise and well counts the number of steps. The distance is good too (I compared over a course which I knew the distance). You can find out how many meters you have run, how many calories burned and even lost fat (in grams). Only problem, it runs all the time even outside a period of activity if you have it on you and it remembers (7 days of memory) that the number of steps taken in a day and not those of a period of activity. But we can not account for a period of activity and therefore see what is spent and gone. I am very happy. Shipping via Amazon quick as usual.
