It is uncanny how this unit tracks the exact number of steps taken. Setup was minimal and very easy. The battery saving shut off works great, no need for an off/on switch. Small and light enough to carry in a pocket. What makes this unit a must buy if you are interested in a pedometer is the accuracy. Once you know the length of your walking stride, which you enter during setup, this unit is dead on the money. You can hold it in your hand and watch the stride count increase every time your foot hits the pavement. If the count is off, you didn't enter the correct length. The advertised 97% to 99% accuracy is not an exaggeration. This unit is like a metronome, it doesn't miss a step. It is eerie to watch it in action. The only feature I would have enjoyed is a wired/wireless capability to upload the stats to a computer or website. Do not let that one item impede your decision in purchasing the Power Walker. Even while driving a car, it knows the difference between vehicle movement and a walking subject. I drove 12 miles to work, the stride count and mileage did not increase.

The price is right, the unit tracks the important statistics, such as mileage, number of steps, calories burned, and more. The unit saves 30 days of data, and 30 weeks of summarized data. You can't go wrong with the Power Walker. I have a phone app which acts as a pedometer, which I used as a comparison against the Power Walker. The app skips steps when it increases. The Power Walker does not miss a single step. It is very impressive. Plus the automatic reset of stats at 2AM is pretty sweet.

This is definitely a unit to own if you are seeking a method of measuring steps per day, which in turn will give you incentive to walk more.

i really loved my old one, this one is a little too easy to reset accidentally, however, that said, it has more features, is just as accurate, is slimmer, and easier to read, its easier to set, but again, I tend to absentmindedly fiddle things and reset it so there we go eh?
For accuracy counting steps for this fat broad, it doesn't give me more or short me, which most other ones do, and the quality is terrific, If your not a compulsive fidgety type, tuck this bad boy in your pocket and you will love it.

3.0 out of 5 stars It is a good pedometer, but not as good as claimed
Reviewed in the United States on January 26, 2016

I have had my ups and downs with the PowerWalker. Initially I was very excited about its functions and it seemed to be working well. Then recently on vacation I found it was off by a mile on a 2.5 mile walk. I adjusted my stride but I find it still logs behind. I tested it by also wearing a pedometer watch that totally shuts down after 10 minutes and does not start up unless i push a button. Even with that feature, the powerwalker falls behind.

I just bought another pedometer and am wearing both (set to the same stride length). It consistently falls behind. I question whether it is as accurate as claimed in consumer reviews.
It is a good pedometer, but not as good as claimed.

1.0 out of 5 stars Total waste of money

This is a horrible pedometer. I bought this because it's consumer rating said it was one of the most accurate pedometers. At times it is very accurate, then others it just goes wild and adds all kinds of steps that I didn't take. Very inconsistent.
Also it doesn't have any way to attach it to your belt or wrist or anything. All you can do is put it in a pocket which is not very user friendly. Most of my exercise clothes don't have pockets.
And the most annoying thing is it constantly resets for no reason. I have put it in my jean pocket, a hoodie pocket, a jacket pocket, and it doesn't seem to matter whether it is loose fitting or tight, it still resets. I have not been able to get a full day of steps since I bought it because it keeps resetting. I bought a small cell phone case to put it in so that I could hook it to my waist band and so nothing would be putting any pressure on the reset button, and it still reset halfway through the day.
I would not recommend this pedometer to anyone.

2.0 out of 5 stars Small - Thin - Lightweight - Accurate for 100 steps. Not So Sure About 2 Mile Walk
Reviewed in the United States on January 15, 2015
Verified Purchase
The bad news first: No data upload to the PC or phone app. Still struggling to get this thing to counts steps accurately over a long distance. The mile indicator is way off.
Details:
I like the RESET to ZERO function. Here are my personal observations.
The EX-510 is much more accurate when hung on a necklace than it is when kept in a pants pocket. Contrary to how the directions say to calibrate the pedometer this is what I did. I counted my steps as I walked for 100 steps. Then I looked at the EX-510 step count. If it was higher than 100, I increased the stride length setting. Then took another 100 step walk. If the pedometer counts lower than 100 then lower the stride length setting. Repeat the 100 step walk adjusting the stride length setting until you get it close to 100. Reality is nothing is perfect. Your stride is probably not exact each time you step especially if you change speeds frequently.
I'm still running tests each day but so far the step count for a 2 mile walk seems off at 4,250. That would be close to a real stride length of 2.5 which might be right but I have the pedometer set currently set to 3.5. Secondly, the distance indicator is way off. It is no where near accurate for a 2 mile walk. These measurements were taken while walking on flat ground with the pedometer hanging on a necklace directly over my chest. I will continue to experiment with this questionable device.
Now for those who could care less about step accuracy. You can use plain math and no pedometer to get to say 7,000 to 10,000 steps per day. This is me: I'm 6 feet tall. I walk at a pace of about 20 minute miles. 4 miles per day equals 80 minutes of walking. The average stride length is between 2 and 3 feet. So 21,120 feet (4 miles) divided by 2 or 3 ft. stride gets you in a range of 7,040 to 10,560 steps. I might raise my star rating in the future but for now I'm disappointed especially how they brag about its accuracy.
Some people like to wear their pedometer all day. If you do that I doubt any pedometer is smart enough to give you an accurate step count. If you don't believe me, then see how many steps your pedometer counts when you drive your car! My friend has a FitBit. She is also frustrated with its inaccurate distance and step count measurements. I guess the name is 'fitting'. You'll have a fit when you use it. I really hope I can come back to this review in a week or so and eat crow but when it comes to distance measurement being off - come on! I tested the distance with a car and a GPS device. They were both dead on. Not these gadgets.
