The lamp I have to request a relatives ordered for you, because it has no PC and no internet access. Since she had already chosen the lamp, I have not so much attention to the reviews, as I usually do it. An error, as this is our attention that the lamp has no on / off switch, which I may depart a star.
Otherwise the lamp fulfills its task properly. The heat development is rapid and reliable, the device appears to be correctly processed and the set screw is also a plus.
