Bought on sale, it's a pretty good deal. Light is small, the light output is not as strong as the other one they have here (with the calendar) but you can easily orient it. Also the color light is bright and will remain at the tint you select. The battery is a bonus, it can be used while there is no power. The USB cable is awfully short and does not come with a wall plug either so I hade to use a USB extension and a DC-USB converter that I had lying around.

Great little lamp. I didn't realize it doesn't need to be plugged in all the time when I bought it. The manual says up to 3 months. Decently bright as to be expected from LED. I will probably buy more of these.

Very versatile lamp. Nice range of brightness levels and long lasting battery.

great for working late at night

Fantastic, handy and cool. Brightness levels provide the right amount of light for working at a desk and won’t disturb anyone if you’re a night owl. Works as a portable flashlight in a pinch. Colored base works smoothly when adjusting the colour and the slow strobing is a cool feature.

Great lightning, the only think I don't like is the power button. When it's dark, you have to tap the base randomly and hope you hit it. Sometimes you will hit the base color light power button which is just below, that is annoying. I do recommend it anyway.
