I have had a number of these devices over the years, mostly in an attempt to increase my activity as I enter old age. The first one broke and the second one was so complicated that I could not use it properly as everytime I tried to alter the time it reset the counter! This one is Japanese ( although made in China!)and unlike most Japanese gadgets is delightfully simple. You press the reset button and it resets. Just like that! It then counts your steps.It also gives a distance measure in miles and the number of calories represented by that level of activity. As I would say if I were an annoying little meerkat, simples!
If you want one of these, this one could be recommended highly. One note of caution, mine is calibrated in miles and feet ( you set your step distance in feet) and there does not seem to be a metric option which I think is rather a shame although fortunately I am bi-lingual in measurement being of a certain age!
