They died after 2 weeks. Something in them tinkled and the screen went blank. They are not subject to repair, because they are tightly sealed from moisture. Pros below: Inexpensive, feature rich, good battery life, bright display Got cons: An inaccurate pedometer, in a dream I could "find" up to 500 steps per night. Arterial pressure is lowered. It is difficult to synchronize with the phone - I had to suffer with the program.
