I can't tell you how the HJ 105 is, but I LOVE the HJ-112!!! I have had 2 or 3 other pedometers before this one and I never really thought there was anything wrong with them. BUT, now that I have this one, I know those others didn't measure very accurately! If you do a search, you'll find TONS of consumer recommendations that say the HJ-112 is THE BEST and it's only about $20!
