To answer questions that some have had that may or may not be explained in product description or by the Rufus question box: Unit uses stand that merely screws in, that makes the clock approx 5 in deep so shelf needs to be that deep*** Battery for remote is provided and is CR2025 available most everywhere and is replaceable ***Power cord is approx 5 ft long ***Unit does not automatically talk but will recite screen only if you press the OK button on remote ***Daylight savings changes automatically by setting country but can be turned off if you live in state that doesn’t use it***can change day and night brightness and the time it changes which also changes day description for example from predawn to morning. ***It came with time set and only a minute off. I wanted it to match my computer time so I left hour as it was, changed seconds to zero and waited for my computer to advance one minute, and moved the minute on clock to match and and exited. Now they both change time within one second. EDIT: IN THE 5 MONTHS I’VE HAD IT, THE DIFFERENCE ENDED UP BEING ABOUT 30 SECONDS. NOT AN ISSUE AND EASY TO ADJUST !*** You can customize wake alarms for days you want to get up for work..for example set time for Mon-Fri or Mon-Wed-Fri or what days you want. If you want to get up at a certain time on other days then set any customized reminder to go off on those days or even use ‘drink water’ alarm and the time you want to wake.***Alarm volume is adjustable and so is duration and can be confirmed by hitting ‘OK’ on remote ***Arrived well packaged. Instruction book has clear instructions with a page dedicated to trouble shooting such as if remote not working, be sure tag is removed from remote so battery connects *** Remote is small, seems easy to lose so I attached a large, plastic clothes pin to the bottom edge of it to make it easier to locate…NOT the top as that would block transmission. Remote functions for me at about 8-10 feet away ***You can set the format of how info is shown on the screen and there are color options.***Seniors with issues may need assistance to get to desired settings *** At this time, I am quite pleased with the item and I ordered a second one for another room hoping they don’t die before I do…HA. Nice that the remote for the first one also works on the second one!!!!! When I unplugged and moved the first one and plugged back in….ALL SETTINGS remained, ***Price is decent compared to others with less functions/options and are without a remote.
