Query: Very disappointed

Maybe none of these type of devices work very well, but this one is no exception. The user interface is very cumbersome to use, configuration is complicated. All we really wanted to do is count steps and occasionally check heartrate. But this device seems to discourage that. The buttons are not very positive acting either, you can't tell if you've pushed them or not. But if you really deliberately test it, it will count steps. I'm afraid it will also count a few hundred steps sitting on the table over night. We are about ready to throw this gem away.
