Light & Function: 5 stars
The light is bright, comfortable, and the setting options are unlikely to be desired (brightness and color can be controlled separately). The built-in USB port is quite useful. As far as very good.
Design: 4 stars
The purist design is a matter of taste, I like it. Somewhat reminiscent of Apple products.
Material / processing quality: 2 stars
The lamp is made entirely of plastic. It also seems a bit fragile and shaky, especially when you adjust the angle of inclination on the various joints. I would have liked a more solid design.
Operation: 1 Star
Really disastrous operation of the lamp is (yes, I have the protective film from the keypad). The touch buttons react very slowly - if at all. By the time you get a better feel for "how" you have to press it, but still it sucks properly. Feels like I press until it actually reacts on average 3x a button. As a consequence, you will sooner or later to use no more desire the many lighting options and allowed to simply be convenience. Very pity.
Only drawback is that you can move only in a standby state when you turn off the lamp. Especially with an energy-saving LED lamp that's pretty counterproductive. But unfortunately seems a trend of our times to be ... If you switch the lamp on a power strip completely, she forgets the last set light options.
What the lamp still "may" is somewhat meaningless switch-off after 60 minutes (including at a desk lamp?). If you use the still, a red light, which can be quite annoying flashes on the keypad permanently. Who thinks something only?
Conclusion: On average, a 3-star rating. The bumpy operation detracts from the enjoyment of the product, unfortunately, very. Anyone who thinks that the good light output but would lead to a better rating, I would counter the still fairly high price: that is simply not justified by the offered material and operating quality. For half the price it might be a 4-star product.
