The delivery was very quick, I was surprised. The lamp has many different settings, so that everyone can find the right illumination for every situation. I myself always use in each of the 4 main modes, the average luminosity (enough for me completely off). The sleep timer also works. The USB port I have not yet tested. I hope that in my opinion, very good quality of workmanship is of long duration. If then also keeps the electronic long, this lamp is a really good product. I would highly recommend the Lamp anyone who needs a very well-lit workspace on the desktop.
