Easy to use but dark

Simply batteries in, press the button and go. Makes a solid impression. No complicated programming, simply select mode and the thing works. so far so good.
Is from the clues that the fairy lights can work three weeks at a time, would have physically have to be clear that there must be a Funzel. In continuous light mode they are significantly darker than the maximum brightness in one of the other modes in which they are also dark. Clearly, you can save electricity here, but Christmas Eve is just one evening. Modes are allowed, but in my opinion a couple of flashing modes should be eliminated and for a Christmas Eve mode (perhaps better market than X-mas Maxi Boost Mode) ago.
Instead of the quick solder itself purely, I got the good old light bulbs light string from the cellar and installed a 230-line with a few detours to the tree. :-)
