Query: OK - Manufacturer needs to build in more durability

Over the years we have bought several of this model pedometer. The unit works well; however, the clip breaks too easily. We had one that broke in 1 week, and we had one that lasted 1 year. It is "hit and miss." Also, sometimes the counter gets screwed up, and the step count is way off.We really like the unit compared to other models. The design and functions are great. We like it even more as the price comes down. (The unit used to cost more than $20) My feeling on all electronic pedometers is that the unit costs less than $0.50 to make (including the chip). Considering the price, the manufacturer could afford to build a more durable model.
