Our Analysis and Test Results

The Updated Ozeri 4.3 Razor Digital Pocket 3D vs. The Old Version

The latest version of this pedometer features a new MotionLock component designed to stop activation while moving in a vehicle. In addition, the Razor Digital Pocket 3D is now equipped with a 30 day memory in contrast to the 7 day memory in the original version. The updated version looks identical to the previously tested version, coming in 3 color options; black, yellow, and blue.

Hands-On Review

The Ozeri 4.3 Razor Digital Pocket 3D is the most compact clipped device in our review. It is slim, accurate enough, and has a simple data collection and viewing interface.

Interface and Data Management

This device shows time, steps taken today, the time spent in activity, calories burned, grams of fat burned, and distance walked. It also shows the number of steps taken each of the seven previous days. As a new day is recorded, the oldest day and associated data is dropped from the memory. For most of our testers, this most recent data was the most relevant anyway. If you get in the habit of maintaining a streak or gradually elevating your activity level, seven days of data is plenty for tracking trends and maintaining inspiration past lighter days. Clicking through the various information fields is easy and intuitive.

If a clipped on pedometer works for your wardrobe and lifestyle, this is a great device. It is thin, compact and unobtrusive. The profile and overall size is basically half the volume of the other two belt-clipped devices in our review. The clip is a low-profile, friction-fit plastic piece. Sometimes the clip and device become separated inadvertently. In order to address this, the Ozeri Razor comes with a lanyard strap to back up the sometimes unreliable plastic clip. As long as your pockets aren't too cluttered, one can carry the device in a pants pocket. The primary disadvantage of this is the potential for accidental pushing of the buttons. Additionally, the accelerometer is not calibrated for carry in this location. As a result, we did not test for accuracy in pocket carry.

In our testing, the basic function of the Ozeri remained viable. However, a portion of the LCD screen has occasionally gone blank. Also, the small buttons times got stuck in the pushed position a few times. In this case, accessing the different data screens was impossible without manipulating the stuck button to free it up. This little bit of manipulation is a minor hindrance. Also, since resetting the step count requires the push of two buttons, the device could in theory be more easily cleared. We could simulate this sort of failure while jostling the device around, but did not have any accidental data-clearing events in our actual use.


With a 1.8% inaccuracy score, the Ozeri scored solidly above the middle of the pack. Whether indicating distance or step count, it got very close to recording the actual data.

Ease of Set-up

This device is easy to setup. The instructions are clear, the buttons are well-labeled, and the required information is minimal and easy. In our testing, we performed the set-up procedure a few times. In all of these iterations, regardless of who did the deed, a complete set-up required just five to six minutes.

Best Application

This is an excellent pedometer for someone who can't or won't carry a smartphone everywhere. If you have and carry a smartphone already, our Best Buy winning Pacer is more efficient. However, if your personal and professional dress code allows for a belt-clipped device and you are looking for very simple activity data for today and the last week, the Ozeri will serve you well.


The closest comparison in our test roster is the Omron Hj-112 Digital Pocket. They both function well enough. The Ozeri is marginally more accurate, and is slightly more reliable. The outright failure of the Omron's "aerobic" mode suggests a less robust product. The higher degree of accuracy and slightly smaller form of the Ozeri is worth a few extra dollars. In short, the Ozeri is an excellent value. It is tempting to also compare the value of the two Best Buy winners. However, the Pacer App and this pedometer are very different products. Their similarity is in the data collected. Both count steps. However, the Razor uses dedicated sensors and can be clipped to the user's belt and forgotten. Only those that are disciplined about carrying their smartphone everywhere will glean relevant data from the Pacer. Anyone who clips on the Razor in the morning will benefit from the information it reveals and collects.


This is a classic pedometer. Wrist-mounted activity monitors like the Garmin Vivofit are generating more buzz and excitement, but for many the classic belt-clip style and simple data interface will be welcome and useful. We give this pedometer our Best Buy award for the best value simple pedometer.
