My son-in-law jus finished building a very large shop with a nice office, for his communications company. He specializes in the installation of all the cabling and equipment. His shop has a lot of space that will taken up soon by racks of materials, equipment and vehicles. I'm helping him install the lighting and some finish fixtures in his office. The one thing that I haven't seen was a clock. In his world, time is money. So, a clock in his shop would be very beneficial. Hence, this really nice, very large and easy to read digital clock from XREXS. Not only does it give you the time, you can also get the day, date and current indoor temp at just a glance.IF you left it on a desk top, you could even set an alarm. But, to me, it's better on a wall, visible from a distance. It was very easy to program. The LCD display uses next to nothing, power wise. So, the batteries will last for years.I'm going to set the clock up in his shop for him. I know he's going to like it. Good purchase. Five stars.
