Question: what is a "false step"?
Document: I ordered this pedometer because I wore my old, mechanical pedometer for a two-mile pace walk at the YMCA, and the pedometer only registered 39 steps. My new Ozeri Pedometer doesn't miss a step. And it doesn't add false steps like my old pedometer. When I was using my old pedometer, I could get between 30 and 100 steps while driving my truck to work.I am in the process of checking the accuracy. Yesterday, I walked two miles with the Ozeri and compared the results.
We own three of these pedometers in the family. Put simply THEY WORK. The greatest thing about the 4X razor is how accurate they are. I am self employed and drive a lot, my son is a city bus driver. Neither of us has a problem with false readings while carrying the pedometers all day. Set up was easy. The only downside to this product is the screen is fairly fragile. A seat belt caught my wife's and flipped it to the gravel driveway and broke the screen.
The Ozeri Pedometer is great! It is accurate and perfect for the 10,000 step program. I give it a 5 star.
Very happy. No problems with the setup. My doctor will be happy that I made this healthily "step". I have a baseline from which I can chart my progress.
Anyway, I would recommend this product to someone how wants to measure time but step into the game of action to miles ahead of their competition!
It took very little to get the step length correct for me.My only wish would be for a USB connector so I could keep track of my steps on the computer.
I purchased this for my son who is training for the marathon. He found it to be slightly off which he felt could be because of change of step size. It was fairly accurate overall and easy to operate.
The pedometer is very easy to set up and use. It seems to be accurate (my step counts are consistent with my usual averages). This pedometer also is not bulky on your waist and does not fall off with normal activity.I'd buy it again.
This pedometer is great. Most pedometors work solely on a vertical axis, meaning that you have to be particular about how you position it, but this ozeri unit doesn't fuss if it tilts sideways or tips over. The result is that it keeps a more accurate step count.
This pedometer does what it needs to do and does it in a compact and nicely priced package. It is very light and easy to keep it on all day; easy to setup. It has a daily and weekly step counter. Controls are easy to use. Highly recommended.
