After I received it I set up the bluetooth, easy enough, then set the time, not too terribly complicated

During the day I have it at its brightest setting, because any lower, the display almost gets washed out from the glow of the sun and its not even in direct sunlight

The bluetooth does work, but if you disconnect your iphone from the charger and leave for work in the morning, your spouse will get a nice set of beeps when you get out of range of the blue tooth as you are leaving for work

It is very dim, and if you set it on a bright setting, all the icons and numbers on the display that are not in use appear as a black outline.

But brightest setting is too bright for me to sleep with, it's kinda like having your phones display on all night, and for me that's enough to have me toss and turn throughout the night
