1) For the cable entry must be plastic out of the holder to be broken and then the enclosed rubber seal should be introduced. This is very tricky and the plastic breaks unclean. The cables are then connected to a huge, fixed terminal which is at a firmer line in very way. Again very fiddly.
2) The bracket on the wall is home not terminal, but the lamp. Especially on the circuit assembly is thus unnecessarily complicated. A Cheap spotlights from the hardware store could be much better mounted.
3) I reach in no case 14 meters. With Anschleichen I succeed even outsmart the motion.
4) Hide non-relevant areas must be carried out with a cheap sticker
5) The adjustment knobs are badly mounted and can not be adjusted with your fingers or a screwdriver.
Conclusion: There is still much room for improvement exists, shame at the high price.
