It is all plastic which I believe will break on the first fall...the brightness in complete darkness is quite good.. there is a magnet on the front part.. I put it on the fridge and it stuck on the second try but the slightest movement can make it fall.. something that is not visible in the photos is that it has a sharp piece of iron to break things.. I tried it on a box and it made a hole.. then on thin plastic and it didn't do anything.. with a little more force it can even stay in your hand.. overall, for 8€ it's fine.
