Installation was not easy because the clamping screw is plastic and not really fixable. I solved this with a better, longer screw and two rubber metal washers and a metal wing nut (~ 2 euro cents).  (See on picture.) The USB cord is quite short, and need a wall charger or a free usb connector. (They not including a power supply). Regardless, these are a nice, inexpensive lamp with a magnifying glass, I can recommend. It has a nice light - although not very strong at the highest level - and magnifies well (at a height of 13-15 cm). Delivery was fast, but the packaging is not very secure, a 1cm thick foam/sponge protects the glass lens in the box ( mine is not damaged ). I suggest you make a video of the unpacking to avoid any controversial issues.

The only problem I see is that the magnifying glass is not 5X as advertised, in reality it is more like 2X
