This puzzle is truly the most difficult puzzle I have got so far (if I don't count "Alcatraz the puzzle", which is another page of the story). The thing about this puzzle is that you don't know where to start from. There are thousands of positions and movements on it, that it feels like a maze. To be honest, I must have been one or two steps away from completely solving it at one point, but I guess I took a different path afterwards. So, at the end, I solved mine with force and one forbidden move, just because I saw the chance to separate the string from the wire. Then, I made a custom string and tried to put it back, but as I had no idea where I had to enter the wire, I looked up the solution. I would recommend this puzzle only to people, who are experienced and have the time, nerves and patience to solve this puzzle. And even if you do - I am sure it will take twice or triple more time to memorize the intended solution all alone (if you are using the intended solution - who knows, there could be more than one solutions).
