I am usually pretty good at these sorts of puzzles, solving most in a a few minutes to an hour. This one has humbled me. Taking it apart was trivial, but getting it back together... OUCH! Day 2, still trying (and doing my best to avoid downloading the solution).

VERY hard to get apart... was able to get it apart 8 days after I got it... BUT I did not spend a lot of time on it each day!

This is the best hanayama puzzle i made till now. It took me a whole day to solve this... at the end of the day my hands were ready to explode but i felt better after solving this. And yeah this should get a difficulty rate of 10 compared with the others.

What's the deal with the Vortex? You can take it apart, but good luck putting it back together! What's the deeeeal with that?

This puzzle is exceedingly difficult. Unlike others, once I got it apart, putting it together was easier than pulling it apart for me. Probably because each time I got further along in the solution, I would backtrack to make sure I understood what I did. I really, really REALLY like this puzzle. But I did hate it for a day or two!

I have to say, this is the most difficult Hanayama that i´ve seen. I thought that Enigma was difficult, but it was not.......

This puzzle is absolutely beautiful! It took me a good while to figure how to take it apart, but since I spent so much time figuring out how to take it apart I was able to put it back together when I finally figured out the last step. I really enjoyed this one! FIVE STARS!!!

Very hard puzzle. Even with the solution it took me a lot of practices to solve it smoothly. Very well designed. Hats off to anyone who can put it back together without peeping!

Wasn't that hard getting them apart... but I'm stumped on how to get it back together!!!! Still won't ask for the solution but darn i'm tempted just in case it will give me a clue how to put it back together. Would love to show it to my Dad but it's a bit ridiculous giving it to him in it's current condition :D

Pretty hard puzzle got it apart can't get it back together for the life of me though.

This is a really hard puzzle i'm still working it i can't get it a part this thing is getting on my nerves.

This is a really beautiful puzzle. Harder to get back together than it is to take it apart.

I had to download solution for this. It was quite hard to solve this even with solution. Really hard puzzle.

Still working with this. I got pieces separated, but no hope to put it back to the original shape. ( i have been close, (??) but still it feels impossible.)

Oh my god, this really should be rated 10 ( or 6 stars in Hanayama). Really hard, i´ve been speding hours and hours with this. I got it "broken" but I don´t get pieces separated neither to the original position. Loosing my nerves :-( Wishes form Finland ;-)
