LOFICOPERDigital Alarm Clock, 6.5'' LED Alarm Clock for Bedroom, Electric Desk Clock with USB Port, Snooze, Adjustable Brightness, Work Day Mode, Black Case and Red Digit

The brightness is perfect, the size and readability is good for my students.

Final add: I bought 2 of these alarm clocks. Today the 2nd clock started doing the same thing but now I am 2 days past the return window, so I have 2 defective clocks that I can't return.Adding that I have had this alarm clock for a few weeks and it has developed a problem. I bought 2 of these alarm clocks and one of them has developed a "shadow" number. It will reas 12:00 when it is 12:00 but now at 5:20 the time looks like there is a backward "6" in front of it. The "shadow" number also changes depending on the time. It is annoying but I don't know if it's worth the hassle to return it or not.This little alarm clock is nice. the numbers are bright (and adjustable) and big enough to read from across the room. There are a few things that are not good. the set up and instructions are confusing. there are so many modes to cycle through that it got annoying trying to figure out what I had to do. the other things involve the cord. first it's a short cord that doesn't fit into the alarm clock well. It kept falling out as I would move the clock to decide on where to put it (because the cord is so short.) The other issue I have is that the cord I received is white and my clock is black. that's nothing to do with anything important but it is annoying to my sense of neatness. one tiny other issue is that the dots on the clock blink. another not very important thing but still annoying.

Works good

The numbers are large and easily read from across the room. There are four different brightness settings for optimum viewing.

Clock was a bit more challenging to set up, and it didn't last long. It worked for only a couple of weeks before the numbers started to distort. Also, it is really bright. It definitely lit up the room. It had a dimmer on it, but it would get progressively brighter as the night goes on and woke up my daughter. We had to continually turn the brightness down throughout the night.

I like it bc I can turn the brightness down.

Nice colors for the numbers but instructions were not clear and showing the numbers to display didn't last but seconds at a time.

i really like this clock! its very easy to read and it works very well..
