These are very cheap pedometers, but even though I find they twist on my clothes, get dislodged, and other things that keep them from counting properly on irregular stepping, I have found that they are as reliable as the much more expensive ones. Some of the more expensive highly rated ones would only count consistent, regular steps - but I wanted something that counted my steps all day, regular or not. This is the best that I have tried, and I have tried many. I have been wearing a pedometer (mostly this model) for three years, every day. They are small, lightweight and don't make a big bulge in clothing (important to me).Get more detail about Sportline 340 Strider Pedometer.
