Optical sure great when they work. The lamps are outside probably much better processed than inside. Half of now a total of 8 lamps needed after removing the fuse strip, plenty of "devotion" to accommodate their work (of course tested in completely dark room). Only removing and reseating the battery, almost all brought to light. For some, however, so that was something to shake again conclusion. A fire still not, even if it is ensured that the battery is full and both sides have contact. Should remain so, some lamps will soon be sent back because of defectiveness. Definitely a beautiful letdown as Christmas was! More than 8 lights there are no means, am already satisfied when 4 pieces and work the gift is thus rescued later.
Unfortunately, the manual is a bad joke. How do you please the lamps 2 Days "off" in the sun to charge, there is no switch, and if you do not remove the protective strip, the battery is not in contact. Also on the possibility to change the battery is not mentioned, let alone the process briefly described.
Since the function is probably the most important thing, unfortunately only 1 star. The functioning lamps would get four stars.
