When I ordered the lamp I thought, for the reasonable price of EUR 11 could not do a lot wrong. Had not paid particular attention to the product description and thought that would be made of plastic. But is not it, in fact it seems almost indestructible by the metal casing! Hell it is for such a small lamp also, no comparison to the old lamps with krypton bulbs that I have ever bought otherwise. For the operation you also need only one of the small AAA batteries and it comes so very long I guess from the operation to nearly an hour. Overall, I am very satisfied, the lamp would buy again.
