Pedometer Conundrum: What is the most reliable pedometer?

Having spent the last year and a half, maybe closer to two years, using pedometers I find myself in a conundrum.  What is the most reliable pedometer?  I have used several different models, just ask my loving and supportive husband, who purchases them for me, and all with a disturbing trend.  The pedometers will work great for about two months, and then fizzle out.  I immediately change the battery and usually carry a spare, so it is not an issue of they lack the proper battery power.  This is an issue where they stop counting my steps accurately.  Every manufacturer represents that their pedometer is reliable, and works well, etc.  What I am asking for is consumer input!  Who of you regular consumers has used the same pedometer for years?  What brand and what make?

I have found that a pedometer is a good structure for helping me keep fit because I can check it periodically during the day and then determine how much more exercise I will need to schedule in to reach 10,000 steps.  The fact that the pedometers have malfunctioned after several weeks of use, without fail, is a real demotivator.  I would like to get a reliable pedometer and I am seeking helpful information from consumers only.  Please DO NOT post a message about a pedometer you are selling.  I'm looking for honest to goodness consumer feedback not the marketing glitz and a sales pitch!  Thank you so much for sharing your feedback and your experiences with pedometers!!  I do appreciate it!
Love,
