If I judge it as a desk lamp, with a large aperture, that costs less than 10 euros, then I have to give it 5 stars.
It has a large aperture, the arms are well balanced with the springs, they move easily and stabilize in the right position. Overall, it delivers what it promises.
Of course, with 10 euros, one has to make some compromises:
- the quality is the minimum possible... plastic everywhere (connectors, clamps, axles, etc.) except for the tubes on the arms, which are actually of decent quality.
- the base is heavy, as it should be, but in mine, it has a problem... it is not even and does not sit well on the table.
- the plastic cap is slightly transparent, depending on the color, but the plastic is not clear... it has imperfections due to low quality.
- it is good that the switch is on the lamp and not on the cable, but its quality does not inspire confidence.
- the bulb goes in horizontally, so the light is somewhat asymmetrical, I don't know if there is an E27 bulb with a large length, but due to the limited space, it cannot accommodate large diameter bulbs.

I think that for this money, lamps with a vertical cap and bulb are better (they are definitely much better in terms of construction), but if you want something more "elegant" with the least possible money, it is an option.

Very fake construction with a switch for laughs, however it looks beautiful and has a good base. After close to a year, it works perfectly
