I look at it, and it just cheers me up. There are some bubbles, and i like them because the bubbles show that it is authentically hand-crafted. Each one will look different -- don't expect them to match each other.
The only mode is on/off, and it is bright. This isn't one of those lamps you can touch to increase the brightness. The boringness detracts from the good shape. The lamp arrived with multiple flaws.
The switch is on the cord to turn it off and on. Great product.
The switch has a short in it and the light will no longer stay on. This lamp *!
