Bests & Worsts Reviews from Amazon

I was pleased with this device when 1st purchased-it did what I needed at a good price. But I am retracting my recommendation after 6 months because the device continually loses its programming resulting in a blank screen. I replaced the battery ,reprogrammed, but the issue returns. The seller replaced my OZO for free in case mine was defective. I have had the replacement Ozo 2 weeks and I am having the same issue of lost programming. So at any time while I am accumulating steps I can glance at the device and discover that it has lost all its data-very frustrating. So the bottom line on this pedometer is short lived reliability. Will be looking to replace it with another brand.
