Fast delivery. The product was well packaged for shipping. Aesthetically pleasing design. Multiple levels of dimming and brightening the light, as well as the option to turn it off. The power button is backlit and easy to find at night to turn on the light. Versatile use.

USB dimmer switch... It's very useful as it has brightness adjustment and on-off functions when lit with USB power. It's a cost-effective switch... Good... I'm willing to buy again.
