I was very excited to get this pedometer. I took it hiking for my first trial. I got to the end of the trail and checked to see how many steps I had gone. It told me I had only gone 20 steps! I noticed that it was slipping off my belt, so I secured it and continued my hike. Along the course of my day, I had the pedometer actually fall off and hit the ground at least 5 times. I got tired of picking it up and trying to keep it secured. I finally just put it in my pocket and forgot it. The round clip naturally slips. It is very frustrating. It could be a very nice little unit, except for this major flaw. I am taking it back to the store.
