Good, it does what it says, with 6 small LEDs and it bends... as it is, it illuminates adequately (for my taste)...
The 4 stars because the cover in front of the LEDs is a bit thick (so it cuts off light), they could have put a thinner cover... if you remove the cover, it now shines about as much as a saving night light... now that the electricity bill is high, I turn off the lights and leave this on top of the laptop, which illuminates the room lowly (when I watch news or movies, YouTube, etc. from the laptop)... however, without the cover, some people might be bothered by it next to the laptop (maybe if they turn it upside down, away from their eyes, it would be tolerable)...
Also, if you remove the cover (it easily goes back in with a light push at any time) and you have a 5V mobile charger with up to 1A (I don't think it will burn it - but not more than 1 amp), connected to the wall socket, you can have a light for emergencies or occasional use, or have a night-saving light for a few hours at night (see an example of a USB in the photo)... the photo is without the white cover (it is next to it) and I have put sellotape to prevent dust from entering
