Ozeri 4x3runner Pocket 3D Pedometer and Activity Tracker with Dual Walking & Running Mode Technology

We purchased eight of these for a year long company walking competition. We are extremely pleased with them.Pros:Battery life - The batteries lasted all year, even with frequent walking and checking of monthly totals. (update: Now had it almost three years and only changed battery once.)Accuracy - I've tested it many times for both walking and jogging. For walks/jogs of more than 10 steps, it is very very accurate. It works well positioned at the hip, in the pocket, in the purse, in your palm (while jogging), or in other positions other than right in the center of your body.Accessories - Something for everyone.30 day step log - The previous 30 days of activity (daily and total step counts) are shown. This is perfect for an office walking competition.Small sizePrice - very reasonable!Durability - I've dropped mine in puddles, I've bumped it into things in the woods. No issues.Quality - No issues in almost three years of use.Cons:No USB, Wi-Fi or other such connectivity features.Doesn't track stairsNote: The pedometer starts tracking steps when you start moving, but doesn't count them until you have gone 10 steps. So if you walk only nine steps and stop, you get credit for zero. If you walk 10 steps and stop, you get 10. If you walk 11 steps and stop you get 11... This is probably some type of battery saving mechanism. I'm fine with it because under 10 steps, you don't get any cardio anyway.

Spent an inordinate amount of time "calibrating" this thing only to have it be the most inaccurate pedometer i've ever used. woke up this morning and verified it was at 0 steps. put it in my pocket and walked to the bathroom and then to the living room, a total of MAYBE 50 steps, and it reported almost 200 steps. walked back to my bedroom and did some stretching (5 minutes worth) and pulled it out... 500 steps. somehow i managed to get a full 250 steps in while sitting still.ALSO: The belt clip is terrible... it's made for a child not an adult. so you'll have to keep it in your pocket. Because you can clip it TO your belt, but not ON your belt. It's not a tall enough clip to surround a belt so be prepared to buy a replacement if that's how you're going to carry itbonus irritation: interface is confusing and annoying

Writing this review from the perspective of someone who wants a ped for accurate walking and jogging distance, but is not interested in tracking cumulative 24/7 movements. Most of the newer brands focus on 24/7 and automatic midnight resets, which is not how I exercise; I like to track/record walking/jogging as discrete events. Amazingly, many of the new models don't have a manual reset--you have to wait for midnight to reset for the next event. What a brain cramp!So good points first:1.Ozeri has manual reset (as well as all the auto 24/7 features).2. After 27 separate walk and 3-mile jog tests, step accuracy in direct, consistent walking and jogging is 99%+ (less than 1% error). For those interested in full 24/7 movements, I would say this ped is sensitive and accurate, but rightfully somewhat dampened so it doesn't record every little wave of your hand as a step as some others do.3. Operating buttons are easy to find but not easily accidentally disturbed, so you won't finish to find you've inadvertently ruined your recording.4. Strong clip. Screen easy to read. Comes with lanyard some might use.5. As is the case with most peds, recording in walk mode begins automatically when you move. But to record in jog mode you have to proactively press Start--a good thing because it ensures your jog data is isolated and controlled. This also starts the timer. You may have to work at remembering to press Start for jogging if you're used to auto starts, but I like it that way.Minor dislikes:1. Instructions say stride input increments are only in gross 0.5 of a foot, which makes your heart sink until you later find that's a typo and it really increments in 0.1 foot. First ped I've had that inputs stride in feet rather than inches, but no problem.2. Having % of 24 hour Goal constantly on display in lower left corner is annoying, 'cause I don't use it.3. Default starting screen display shows time of day and steps, whereas I'd prefer to have default show steps and miles.Overall an accurate, sturdy, nice-looking ped.

Wanted a stand-alone pedometer rather than depend on step count function on my iphone which is too big, bulky to be always carrying 100% during the day. Love this device because i can detach cords, skip the hip clip, etc. and just keep the device by itself in my pocket -- and it keeps an accurate step count all day long, 100% of the time.Pedometer count technology has definitely improved since my prior 15-year old model which had a weight jiggling up and down, and I believe would only work if clipped to my hip on belt.
