Query: Exceptionally low quality

This is the worst watch I have ever owned, almost no feature is designed in a reasonable manner. The buttons are over sensitive, making it almost impossible to get a single click. I would often need to stall in mid-run in order to get it going or halt it on water stops. The operation system is ridiculous, the time setting feature is on the same cycle as the time and stopper, making errand bumping the time almost inevitable. According to the temperature reading Chicago has one of the most temperate and stable climates around the world (exactly 74F). Worst of all, after the first drops of rain the clock just died (i.e. no display, no sound no response). The only positive thing I can say about this product is the external design is convenient if you like to clip your watch on your running gear.
