Do you really like Capacity IBM High 75P5427 ?
I was impressed with the reviews prior to purchase. The HJ-112 is impressive and appears durable. I have had it about three weeks and use it every other day on an indoor measured track. The steps appear to be accurate enough, but the mile measure, even after numerous recalibrations IAW the instructions, does not measure very close. This is disturbing as I had planned to use it for distance tracking. I would recommend it only for steps, and that said, I would not buy another just for that purpose.
