Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

I was a little disappointed in the original Tangram Cube because there's just not that much to the solve. It consisted of only 3 steps and 2 of them were really easy. I'm still a fan of the overall design though so thankfully the 'extreme' version of the Tangram Cube introduces many new elements to the solve while still feeling like a Tangram Cube. It still has the same turns, the same 3 edge turns and same 2 corner turning layers, but new cuts allow the edges to now turn while the corners are offset. Not only does this create new pieces that are not present on the original cube but it also means the cube can now shapeshift as pieces can be jumbled into spots they don't belong. It provides depth to the solve that the original cube lacked.
The cube can be solved with a single simple alg, just like the original, but the difficulty lies in understanding the correct order of what pieces to solve next. Which is not easy when everything is all jumbled up and small triangle pieces look similar to other small yet different triangle pieces. It's a fun solve working through the logic of it and even knowing the solution it's fun just to do it. There's no orientation to worry about, just get the pieces where they need to go.
I have to deduct a point for how often it locks up though. There's lots of pieces of different types sliding across one another and getting stuck while turning is very common. It also can be annoying handling a cube with lots of sharp little pieces sticking out. There's a lot of little triangles on this cube and because it can shapeshift that means there's a lot of sharp little triangle points sticking out everywhere. It's not going to cut your hands up but it can be annoying at times to handle when you can't even grip it without getting poked.
Overall a huge improvement over the normal Tangram Cube regarding the solve but a step back regarding how it handles.
