Product Description
Presenting the newly updated 4x3razor Digital Pedometer by Ozeri - the world's thinnest and most advanced 3D activity tracker. Unlike traditional pedometers that do not work accurately unless secured vertically, the 4x3razor utilizes a new advanced 3D Bosch sensor from Germany with Tri-Axis technology that provides superior accuracy in any orientation, whether up, down, flat, on its side, or at any angle. The 4x3razor's Bosch Sensor is a digital accelerometer which is far more accurate than mechanical sensors found in other devices. Compact, sleek and razor thin, the 4x3razor Digital Pedometer is only 0.5 cm (less than 0.2") thick and weighs just half an ounce to fit into the tightest pocket. It includes a detachable lanyard and belt clip for the ultimate convenience. A personal trainer par excellence, the 4x3razor is used by professional 100 mile ultra-runners to accurately record steps, distance, calories consumed, fat burned and exercise time. This advanced digital pedometer counts up to 1 million steps with 30-Day Memory, and includes a built-in Clock and Sports Timer with Auto Sleep technology. The 4x3razor now features MotionLock to prevent unintended motion detection, such as when traveling. It also filters out vibrations and only begins counting after it detects a sequence of continuous steps for greater accuracy. The 4x3razor Digital Pedometer ships with an installed and extra Lithium battery, a belt clip and detachable lanyard and instruction manual. Your satisfaction is 100% guaranteed.

There was a problem filtering reviews right now. Please try again later.
Setting it up was very simple. I wasn't sure of my step length though. I first set it up to 2.5 as recommended by the many reviews but after testing a few times on a treadmill, I lowered it to 2.25. At 5' 4" tall, my step length is not too long. I would have like it if I could set it in 0.05 increments, but 2.25 is close enough. I walk on the treadmill a lot so have done some statistical analysis of what the pedometer tells me and what the treadmill reports.
I've note down the information after having walked 1.05 miles on the treadmill at different incremental speeds. At 3.6mph and 3.7mph, the Ozeri pedometer is almost right on. As I increase the speed of the treadmill, I take larger steps so the accuracy go down, but not by much as noted below. The only discrepancy is when I ran at 5.5mph. My strides are longer so the Ozeri did not count correctly. I have to note that this pedometer is not made for joggers, but for walkers. It does its counting and statistics calculation extremely well in the latter.
Brisk walking (time, miles per hour, steps counted, miles reported, calories burned)
* 17min 45sec, 3.6mph, 2450 steps, 1.04 mi, 104.6 cal

Another thing I noticed is that if I walk slowly and infrequently and although the pedometer would report many steps by the end of the day, the calorie count would be low. It reflects my infrequent steps. I could take 10,000 steps a day and burn less than 200 calories! Where as if my steps were sustained within a short period of time, the calorie count would be much higher. The same 10,000 sustained and continuous steps would show around 400+ calories burned! This pedometer wants you to move.
What I like about the Ozeri 4X3 Razor:
+ Counts silently
+ Counts even when in sleep mode (no display)
+ Memory retains up to 7 days of steps
+ Calories-burned count is differentiated between infrequent stops and sustained steps
+ Accurately counts distance walked (provided that you set your stride length correctly)
+ Does not matter where you wore it (be it pocket, belt, over neck), it counts
+ If you don't wear a watch, you can use it to check the time
+ Durable... it probably fell a dozen time when it slips out of my hand or when it fell out of the belt clip, but it keeps on counting
What I didn't care for:
- I wear it on my belt a lot and sometimes when I run, it would slip out of the belt clip and fall to the ground (my solution to this is to stick a little bit of double sided tape on the back area between the clip and the pedometer).
- I would like to be able to set a "reset" time as I sometimes still exercise after midnight when it resets to 0 for the following day.
- I would like to be able to set the stride increments of "0.05" instead of "0.25"
I read some reviews on how easily the face of the pedometer is scratched. I solved this problem by trimming a cheap cell phone LCD screen protector and sticking it onto the Ozeri. Not a single scratch since I did it.
It has been roughly 40 days since I purchased and used the Ozeri. So far, it counted 520128 steps! I bring it with me everywhere and have challenged myself to walk as much as possible. You would be surprise on how much more you would walk if you give yourself a goal everyday. Overall, I love this little unit and would definitely recommend it.
--- Update 9/17/2013 ---
Just an update on my Ozeri pedometer. As of 9/17/2013, the pedometer is no longer working. I've owned it for a little more than a year. I guessed one too many drops earlier in its life did it in. The pedometer still works but the LCD is no longer displaying information. There are a bar here and there, but nothing that can be read. It was great while it worked.
As a reminder for others who walk/jog a lot using this pedometer; if you use a belt clip, I suggest you add a little piece of double stick tape in between the belt clip and the pedometer to prevent it from sliding out, causing premature malfunction like it did mine.
I would rate this a 4.5 if given the choice, but I dont have it, so I have to round down.
Positives:
+ Very small and lightweight. At times I tend to forget I am wearing it.
+ Programmable stride length.
+ Keeps an accurate history, and has several different modes to track. (Steps, distance, calories, etc.)
+ Nice and sturdy clip.
+ I suppose its nice to have the lanyard, but I honestly don't use it.
+ I LOVE the fact that I dont have to reset my steps the next day, it automatically starts the steps over based on the clock (Best feature next to the size IMO).
Negatives:
- I didn't like the fact that after I initially wore it, I couldn't figure out how to get back to the "initial" setup, where you set your stride. I had to use the "reset" button to do this.
- The buttons on the sides and top are small, but the whole unit is.
- It seems a bit tricky to get it to show the steps up, if its not actively showing. You have to hit the mode button a few times to get it to come up. Good for battery life, but it does take a bit of clicking to show what you want.
Overall the negatives are really minor in my opinion, and the major piece to me was not being able to go back into setup from what I can tell. The little guy does a good job, I've used an ipod nano pedometer to track it and they were very close. Its using the same sort of tech in it, so I definately feel confident about the numbers. I actually enjoy the fact that it doesn't have wifi or syncing. Its a bit of high tech, without being overly electronic.
The best thing about it, is you just clip it on in the morning, and dont think about it until you check on it later. I have confidence in it, and most of the times I forget I'm wearing it. To me the convenience of not having to reset it every morning, and knowing that it is accurate is worth a little bit more. Its a bonus how small it is. I dont regret purchasing it, and if you are looking for something similar I dont think you will either.
*EDIT* I've used this thing for about a month now, with over 200,000 steps logged on it, and I'm definitely happy that I got this one over a cheaper model. Many times when I am wearing it, I have to feel to make sure that I still have it on. It just seems to disappear. There was a little bit of a concern that the clip wasn't going to be as stable since it moves a little bit, but it hasn't failed me yet. I'd call this a solid 4.75, and that was only because of the slight annoyance I had with the reset after first purchase.
*UPDATE* This broke for me after having it for about 6 months or so. However i'm going to be ordering another one. I did drop it, and seem to have broke it... I still am impressed enough to buy again, but probably feel it shouldn't have broke.
