The device lights up all over the green turn when 1 minute remaining on the clock and turn red in the last 10 seconds (then cycle through all kinds of color ringing). Although this is a little gadget, you end up enjoying this little button.
If for some strange reason, you must use the timer in the dark, you can force the illumination for a few seconds by pressing a button (and for this purpose, the color of the illumination can be programmed)
The rear of the device has a magnetic flap with 3 points (from COUPONS magnets hold well) to attach to a refrigerator or a hood. You can also fold this flap to flatten the back of the timer and lay it flat on the work surface (the side of the device is thus slightly inclined)
The screen is sharp, with large numbers we can easily read at a safe distance.
The device can both count down that amount, as if it triggers a set space or 00:00.
