Love these for lighting up the floor of my big truck or plugged into a powerbank for camping as low level tent light or flashlight.easy to use,lots of colors

I've had these for a couple of years and never wrote a review. So they've actually held up. That is a plus in and of itself given the shelf life of many tech gadgets these days. I don't remember how much I paid, but I saw some cheaper variants after I made this purchase. I don't regret this purchase given that they are still working after about 2 years.They are very stealth, so they blend in pretty well. I feel they are decent quality and are very colorful. You have the option to cycle through several colors (I believe there are 7) to match your mood or the interior of your car. You can choose a single color and adjust the brightness or just have it cycle through colors along with adjusting the brightness for the cycling.The device stores the setting, so when you turn your car off (or the power source) and turn it back on, the previous setting is stored. There's no need to setup your color scheme again.Unfortunately, I can't provide feedback on the daylight sensor (they aren't supposed to light up when they sense external light). Mine are located in a cubby which doesn't see external light, so they stay lit all the time.

Small usb that add good small light to my car.

I'm using these for edge lighting on small acrylic pieces. They are the perfect size and brightness for that. My only complaint is that the instructions on the packaging (which you can also see in the product description) aren't completely clear for how to change modes. Once you figure those out it works great. Here is a written translation of the "How Set It" instructions:Color setting: A quick press and release moves to the next color shown in the loop.- The change isn’t instant. It fades out then fades in to the next color.- The LEDs will stay fixed on that color except for the red color that comes just after white. Stopping on that color will continuously cycle through all of the colors, fading in and out of each one.Memory: Holding the button longer than 10 seconds will store the current settings in memory so that those settings will be the default after losing power.Brightness: Holding the button slightly more than 2 seconds will decrease or increase the brightness.- This only works when in the “fixed” (not pulsing) mode.- Ignore the “<2s” note in the instructions. Hold the button for about 2 seconds. The brightness will start pulsing. Release the button when it’s at the desired brightness.Dynamic vs Fixed mode: There are two modes, fixed and dynamic. Double click the button to toggle between the modes.- Fixed means the light will stay at the same brightness all the time.- Dynamic means the light will continuously fade up and down in brightness.- You can’t toggle between fixed and dynamic modes when the colors are set to cycle.There's a photocell near the button. This is used to automatically turn off the LEDs off when it's bright out. As far as I can tell there's no setting to disable this, but you can always put electrical tape over the photocell.

Pretty good quality for the money. Lights up the interior just enough. Nice to change colors

Good price

These are neat, but not very bright. I guess I really didn’t know what I was looking at when I clicked “purchase now”

The instructions are sort of obtuse, so here's my take:Quickly press and release the button to change colors. Colors include Red, Orange, Yellow, Green, Cyan, Blue, Purple, White, and an automatic color change/rainbow setting.Hold the button down to change the brightness. Release the button when the brightness is satisfactory.Double click the button to have the brightness continuously ramp/pulse on a single color.Leaving the unit powered on with no further button presses for more than 10 seconds will cause that setting to be saved for the next power cycle.
