The pedometer itself is pretty good.... however, mine did not come with a battery. The instruction manual said that a battery was included. Since it was a weekend, I went out and bought a battery for $3.99. On Monday I called customer service at Omron and informed them of my missing battery. They said I had to return the unit to them for them to install a battery and ship it back to me. I told them I had already bought the battery and I wanted a credit or another battery to use when the current one expires. They said, "Sorry, you have to return the whole unit." I told them that was the dumbest thing I ever heard.... spent $5 to ship and be without the unit for at least a week. "Sorry, you have to return the whole unit." The next day I called back and asked to speak to a manager... got the same story, except they would send me a pre-paid mailer. NO THANKS! I may never see the unit again the way this company operates.
