Okay, for the price can not expect too much you. The lamp comes with an insert for batteries, alternatively, you can operate it with the old Sony camcorder batteries. The idea is not bad, especially since it has often been lying around from old DV cameras such batteries. However jammed immediately after inserting the battery in the holder, and was difficult to remove again. The whole lamp looks very shaky and made easy. For the hot shoe, I find it a little too big. Overall, for the price probably ok but I will prefer to invest a little more next time.
