The Troy 3D-Star is a 3x3 shape mod that resembles two pyraminxes fused together. The challenge is understanding how the pieces are supposed to align in the solved state. A very fun and innovative design from Troy Robinson.

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.

This star cube is very nice and turns very well, other than some lockups because of the many pieces. Overall, very fun, but not a single video on YouTube of how to solve it.
Although it turns smoothly out-of-the-box, it will often lock-up (or turn the wrong axis) if not properly aligned. I like the colorful high-quality stickers, but there are only 4 colors (for 24-sided polyhedron)! In my opinion, it should have at least 8 colors. The way it is colored, every "edge" piece is duplicated twice, so there are FEWER combinations than a standard 3x3 cube's edges. Unlike a standard 3x3 cube, the orientation of the center blocks DOES matter. I haven't done done the math, but my engineering estimates consider this, overall, to be nearly as difficult as a standard 3x3 cube.
Four of the corner blocks have the same color as the other four corner blocks, but with a different order. For example, if one corner has color Red-Green-Blue, then the opposite corner will have color Red-Blue-Green (when listed clockwise beginning with Red). I guess the puzzle designer wanted to confuse people with color-order (and save money on sticker colors)?
More importantly than color, the middle/slice layers are too thin. Not only does this make facet stickers small (especially at the "centers"), it makes manipulating the puzzle with "slice" moves difficult at best -- totally impossible for speed-solving. From my engineering background, I see no reason why the middle layers couldn't be thicker. Such a change would ALSO make the puzzle more aesthetically beautiful! (Currently the corners are "thicker", but expanding the middle layers by just a bit would make them all symmetrical!)
In summary: this is a very unique-looking puzzle, but design choices reduce # of combinations (easier than expected) and frustrate playing (skinny middle layers and lock-ups). I can only recommend it for a collector.
I solve using beginner's 3x3 method. Can be challenging to follow the colors. The centers of the middle layer rotate, and must be rotated properly during the first layer (similar to the windmill cube). Definitely a fun puzzle! I recommend it.
I love this puzzle, I was making good headway on a solve but I then noticed the center/base of the triangles. Uh-oh's. Back to the beginning.
This puzzle is a lot of fun.
I'm pleased that the quality of the puzzle over all is so high. Well worth the investment. OOTB, I was more focused on the appearance, weight and shape.
This is so difficult though, I'd give this an 9 out of 10. (And I've solved a Morph Egg)
This looks better when solved, which is reason enough to solve this one.
If you enjoy a solve that requires some planned moves, for example a RediCube or PetalsCube, this is the next step up.
I love it in my collection.
