Marathon USB Clock Charger with Black Finish (CL030063BK)

C. D.: Well designed little desk/table-top clock with a lot of info on the readout. The instructions allow you to change the color and the brightness of the display. Angle is adjustable. Love the 2 USB charging ports. Price is pretty good too. It would make a nice gift.

Amazon Customer: The only thing I was looking for in this clock was an alarm that did not turn itself off after 5 minutes. Because I use it to take my daily medication, it's very important that I turn the alarm off after I have taken it. I even posted a question to the seller and it stated that the alarm had to be manually turned off. And, of course, it turns itself off after 5 minutes. I've now been late taking my medication 2 days in a row, with the usual onsetting side effects. Very disappointed in this purchase.

Aaron: I want to like this clock but the display is just too bright. It has three settings:

Bright - fine during the day
Dim - still too bright at night
Off - not sure why this is even a setting

Everything else seems good so far - but the display is just too intense in a dark room.

Bob Petersen: Even when on the lowest setting it's still to bright at night...

Garth Wood: The main digits for time are almost 4.5 cm (1.75 in) high and easily visible, lots of colours to choose from, the temp and humidity indicators appear to be reasonably accurate, and the price is absolutely *unbeatable.*

Quite satisfied.

TechnoDogSG: I purchased four clocks. Out of these one had a broken power adapter and another one faulty temperature sensor. Overall I like this clock. It is easy to operate and I like the ability to change the display color.

One problem is that the display becomes much less readable if the clock is above your eye level. For example, if you are laying on a bed and the clock is above you.

Joey NYCJoey NYC: i got two of these from the same 1116 lot (what they ship in 2021) and returned one for refund (thanks Amazon). clock accuracy may seem silly when you consider you'll need to time change these manually every 6 months, but i needed a second hand i could trust for financial market watching reasons. (against NIST) one clock was 10 seconds fast per month while the other clock was 2 seconds slow per month, so it would seem getting an accurate crystal is a crap shoot here.

i used a salt bath calibrated B07YY1FB9D (which was double checked against nearby weather service readings while in the shade outdoors to further confirm accuracy). i determined that one humidistat was wild and seemed to report random numbers ±9% while the second one was +7% at low humidify and +5% at high humidify, which means if i could manually recalibrate this clock then it's humidity% would be reporting fairly accurately.

accuracy junkies like myself should be patient with any device you buy, as you need a few weeks of observation for the humidity% to refine a bit on any new humidistat. be advised if you live an a dry climate, this clock reports "LOW" once under 20% and considering it's calibrated...

Dragon: I do like the advertised features of this product. There is one thing that I would like to stress: 1) For the alarm, there is no volume. It comes standard as “WAKE UP” and shut me up or have a terrible rest of the day!

T. Davis: I love this clock! It's display is bright and easy to read. Has time, temp, humidity, date and all are readable. I can easily see the time at night without my glasses. I have it on a nightstand beside my bed, so I don't have it shining in my face. I don't think it lights up the bedroom all that much. When I ordered it, I thought it was pricey, but I knew I could return it if I didn't like it. No way I'm letting this thing go. I've hooked my iphone up to the usb port to charge it and have had no issues. I use the optional color display and just let it drift from one color to the next - it's really neat!
If there's a con to the clock, setting the alarm in the dark is not going to be easy. The buttons are small and are on the back. Wish they were on top. Not an issue if you use the same alarm time every day. There is a button on top to turn it off / on that's easy to find in the dark. I would definitely buy again.

Ronald M. Chavin: Defect #1:
This clock can be wall mounted but only with great difficulty. The reason is that the power cord comes out directly from the back. Therefore, in order to wall mount this clock, a 3.0-inch shelf would need to be created on the wall.

Defect #2:
Marathon shows a misleading photograph of this clock displaying several colors at the exact same time. After receiving this clock from Amazon, the buyer will realize that this clock can display only 1 color at one time.

Comments:
This is a great clock for showing off and impressing your guests. The light blue color is especially beautiful and might very likely become your permanent 1 color. The "Auto" mode can be left on indefinitely and causes this clock to automatically go through all 25.6 colors - but it can display only 1 color at one time.
