So, I wasn’t sure if this was just going to be a pyraminx by another name, but, it was cheap so I decided to buy it. Turns out it’s way more challenging than a pyraminx and if I’m not mistaken more challenging than a 3 x 3. I think I solved my 3 x 3 for the first time quicker than this puzzle. This has been a very big challenge for me for whatever reason. I decided to get a second one so that I could take it apart because I just really couldn’t tell which pieces were the center. Turns out that was a great idea because I can figure out the effect of an algorithm so much quicker if I can take the puzzle apart, put it together worked and then do the alg and make notes on what happened with it. That being said, I have taken this cube apart at least 35 times and I still haven’t had anything to pop out or misbehave in any way. it still turns well. not as good as my one that I haven’t taken apart yet but it still turns just fine. I have an idea than when I quit taking it apart and can do a proper lub it will go back to feeling just like the cube I haven’t taken apart yet.
