He has good buttons and a clear display. Nevertheless it weighs only 20 grams and is close enough to be discreet pocket or bag. The accuracy is to go with a 2D sensor which works very well and allows a very thin object with low positioning constraint: in a pocket, around the neck not worry the device will work whatever its position; in a bag, just avoid putting flat into the bag and instead position it in a pocket at the vertical or side. The 7 day memory, the ability to separately measure a year, the challenge of 10,000 steps daily, so give this a pedometer excellent quality / price. Add to this that the battery is given for a period of 1.5 years is three times that competitors ...
EDIT: after several passages in machine at 60 ° C, I confirm that the unit is perfectly sealed and particularly strong! This confirms the 5/5. The battery held a little over 3 years!
