After I bought one of the lamps on the desk of my son and was delighted with the quality and luminosity, I bought 2 more copies for our bedroom. The 3 brightness levels are very well thought out - at the highest level you can read comfortably. For the money you get at the hardware store in the department LED lamps only scrap. This lamp is stable and works quite wertig despite plastic case. The power supply also does not whistle, so the lamp is fully compatible bedrooms. Just a pity that there is not the model in other colors, such as black. The switch is large and even in the dark easily palpable. In order to switch the main-LEDs sitting the color ring: the bottom on / off, the remaining ring to adjust the colors of the lights left and right in the bottom of the lamp. I have nothing to complain about, so 5 stars.
