Unfortunately, the laser is completely useless because not even holding the screw of the battery door. 5 seconds used already jumps out of the lid. At sure the laser would ok, but the screw is simply allerbilligstem plastic which has no rational thread. I'll return the items, because I do not want to support such an audacity. Clear cost of laser only nen Zehner - a screw cap made of metal with a usable thread would the price but not astronomically drive up. Amazon would I advise you to take this product out of the range.
