This is one of three pedometers that I've been trying for professional reasons. If one bears all 3 together, there may be deviations to 50%. For pure walking (and even while jogging) are the differences in the acceptable range (max. 10%). It is not that always the product more and the other always displays little ... Therefore: route calculation, calories burned and similar gadgets is hard to use. I would opt for a product that can be worn well with its own activities (counter must not depend too weird!) And just accept that in mixed activities (bike ride to work, driving, etc.) out the result is not very accurate. But surely I can distinguish good from bad days. It is nice if you want to measure distance walked at a current activity (how many steps does this walking route?) - It works well with all appliances. However, be careful:. Counter attach to the fuselage, otherwise it counts ev only every 2nd step (clearly if he were on a ankle, he would not step the other leg noticed) This model: can not attach very good but a bit for people who wear it as a pin, for example in the breast pocket of a shirt. Meter does not adjust automatically to 0 - Advantage: can be done individually. Disadvantage: if you forget the provision can be established only with arithmetic, how long the route was - if you had written the old value. General impression: cheap packaging (blister), not exactly inexpensive product - was no better than one which was 20 cheaper.
