I sadly had to return this item due to 3 issues.

1. This watch has button guards around the buttons.  I guess this ensures that it does not press and activate while in your pocket or wearing gloves.  I found this makes me really focus on button presses.
2.  The barometer is really accurate from my testing of it, but the digital graph screen was too small for me to really find it useful. I wish they had a mode that would fill up the screen with the graph reading  A lot of other ABC's watches have this feature,.
3.  I had to press the device about 30 times before it even attempted  "GET" to read the atomic signal. Not sure what caused it but once it worked it worked.
