The mf8 Sun Cube is a 3x3 shape mod in which each of the sides resembles a sun. The puzzle can be turned like an ordinary 3x3, but it can also be turned when the layers are at 45-degree angles relative to one another, which introduces many more turning possibilities.

Our Promise to You
All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.
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.
The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

Awesome puzzle, but it does have it's flaws. Out of the box, I was surprised, it seemed to turn quite well but my oh my was I being fooled lol. I scrambled it up and after getting it back to cube shape I started noticing some issues. My two biggest problems were luckily fairly easy to fix. The center caps may as well have had fans behind them. Even the tiniest catch and one of them was popping off. Luckily the entire center piece is the correct color, so finding the proper place for the cap was easy. A few small pieces of paper under each cap fixed that pretty easily. However, the bigger issue was with the center pieces themselves. The friction inside between them and the core caused them to not rotate. So with a lot of turns, the pieces would rotate around the center rather than the center turning with them. This caused some odd lockups and just overall annoyance. Finally after getting more than tired of that issue, I busted out the tape and lube. I took each side of the puzzle off, taped together for easy reassembly. I cleaned and lubed the core and the pieces. After complete reassembly and a little bit of tension checking, I was astounded! It was like a completely different puzzle experience.
The puzzle solve is fun, although a little complicated. The indents on the stickerless kite shaped pieces make it easy to see where the bandaging might happen, that is once you figure out why the bandaging happens.
Overall, it's a very fun puzzle. Be prepared to spend a little bit of time and TLC making sure that it works a little better than out of the box. I'd say that if you're an avid solver that likes a new challenge then this is a great puzzle to grab. Not heavily algorithm based and the new ones you will need are fairly intuitive if you have a decent amount of puzzle knowledge.
This looks like a more symmetrical (not-bandaged) version of the Unicorn Cube, which I liked (and what motivated me to buy it).
This puzzle looks nice, although stickers were not best quality. As in prior MF8 review, the stickers on corner blocks have visible X crease marks. However the stickers were the least problem...
Although it looks like Unicorn Cube, the corners do NOT twist. You can play it like regular 3x3 cube (from my limited experience) but the unique thing is that instead of twisting faces by 90 degrees, you can turn by only 45 degrees. This results in shape-modification and "bandaging" issues.
Sadly that is all almost everything I can say for sure...
This puzzle IS well lubricated out-of-the-box, but it still seems to catch when performing standard face turns...
Out-of-the-box the tension was very stiff (although well-lubricated). I decided to "exercise" the cube to HOPEFULLY make it easier to play...
I spent about 2 minutes turning a single face backwards and forwards (between 90 and 180 degrees)... no corner cutting or slice moves... just turning one face... and, without warning, the puzzle DISINTEGRATED!
I have NEVER experienced this before. It is not like 1 piece popped out... multiple pieces popped at once and I was left with a lap-full of about 10 pieces... and I had no idea how to fix it...
I tried putting the pieces back, based on size/color, but the remainder of the puzzle continued to disintegrate. So now I have 3/4 of a cube and about 20 tiny blocks in a pile of rubble!
I really WISH this would work, because it looks cool and fun... but mine self-destructed in less than 5 minutes. Not recommended for anyone.
Don't be put off by negative reviews, this puzzle is very fun and turns very well considering how complex it is. It does catch often but rarely pops unlike the Dayan Bagua cube which is very unstable and explodes. Out of the box, the Sun cube was a bit stiff but after several solves it turns very smoothly. There is internal bandaging which bandages the cube exactly the way the Bagua cube becomes bandaged by the orientation of the strip pieces. The difference is that the pieces are internal and there are semi-circular notches on each "kite" piece to guide you. So compared to the Bagua cube, the Sun cube is a little easier. There are also third-party stickers available that better show the semi-circular notches if you decide to go that route. I highly recommend this puzzle, especially if you're deciding between the Bagua and this one, definitely get the Sun cube instead.
This is another puzzle I really want to work. The idea is intriguing and seems really challenging to solve because of the jumbling. The problem is it is impossible to move without it catching and I usually lose track of the moves because it won't move as expected and end up losing a solve because of it catching too easily.
Sort of like a simplified Bagua cube but more stable. I would recommend the stickerless version since, unless they have changed the stickers, the internal bandaging is hidden on the stickered version, although you can find stickers that show it from a third party. This internal bandaging adds a degree of difficulty to the solve. A great cube to own.
