I have the Omron pedometer now for about 4 weeks and use it daily. Plus points are the small compact shape, the simple (one-time) data entry and reliability. However, because you have to distinguish between the areas of application: When using "outdoor" Everything's fine. If you as a distance count the previous steps and then compares the information from the electronic Helpers, are wrong (at least in my copy) exactly match. When using "indoor" I have my doubts. Example: After getting up I checked first the zeroing of Omron and then I went into the bathroom (just 28 steps). During the inspection, but the device was more than 70 steps. On other occasions there are these differences. When I sat down yesterday after walking, the count stood at exactly 15,667. I'm definitely not gone the next hour a step, I would have expected that the count does not change. But there have been added at this time still about 100 steps. What bothers me is that not because these differences fall absolutely not in my average Gehleistungen between 10,000 and 20,000 steps into the weight. Regarding the addition displayed values are the "nice to have", as the saying goes. Whether you want to be trusted unconditionally, everyone must decide for themselves. This applies particularly to energy consumption. I personally stay there a bit skeptical and use these values only as a very rough guide. But that is true for all fitness equipment, not only for the Omron. When the device according to the manual used (right position!), It has no problem, at least in the outdoor area, so. Anyone looking for a reliable pedometer for a reasonable price, is well advised with Omron.
