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 cube is a great budget cube for beginners, but do not play this cube when you are standing, or having a distance to the floor because if you dropped it, it will explode and it is a torture time to pick the pieces up and reassemble it back. Trust me, it is the worst.
So I didn't buy this cube, but I tried it at school. overall, the cube is really smooth, buttery and fast. I didn't undershoot overshoot, or pop the cube. Very stable, and amazing. Defiantly buying this cube. Also a good price. USE CODE JRCUBER BTW.
So I had this for 3 days and then when I was at school I hugged my friend goodbye and dropped it then it exploded. It was amazing and a couple people helped me pick up all the pieces but I lost one. So I’ll probably buy a new one. But the actual cube. It turns really nicely but has a bit of a catching problem but not to and and even though it’s a big cube it’s worth saying that it doesn’t corner cut well. Also this was my first 7x7 so I don’t have one anymore. Just a bag of plastic and stickers.
Out of the box, this thing is a monster to turn... but, literally loosen the tentions by a third of a turn and you’ve got yourself an amazing 7x7! I got this in black... and I dropped making the core snap... but that was my fault. I just want to say that you should do your 100% best to not drop it. So I bought it again in stickerless, which I think has a great color scheme. I do not reccomend buying it stickered, because when/if they peel, good luck restickering! XD
Overall, 4.6/5 for me. Thank you, MoFang Jiaoshi!
This was my first ever 77 and it was awesome... The tensions where perfect and didn't have to mess 38th them. I don't practice very much on big cubes but i did break it in with about 25 solves and still AMAZING for a $20 cube!!!!!!!
Corner cutting. 9.5/10
Lock ups. 9.5/10
BUY THIS FOR BEGINNERS OR PRO'S PLEASE IT IS SOOOOO WORTH IT!
Perfect (for my skill level) right out of the box. Buttery smooth and no popping. If you are looking for your first 7x7, try this one, it's great.Nothing else to say.
I wanted a good 7x7 because I have a cruddy V-Cube that is horrible. This was a cheap cube but with some Lubicle 1 it was better. I bought the lube for my Shengshou Aurora 5x5 but I needed some for this 7x7. Overall an 8 out of 10.
Great without adjustments, lube only. Center is a little tricky because the tiles seem slightly too small for my hand but it's not a big issue. I enjoy using this cube.
I just unboxed the MF7S and I absolutely love it! It turns very smoothly right out of the box (please note - I bought it with the Cubicle Pro Shop lubing service). It did come quite tight though, with a pretty sluggish feeling (yet it is very smooth) and less than 1 piece of corner cutting, which I suppose is sub-par, but still enough to satisfy me, considering I am not a 7x7 speed solver and this is my first 7x7. If you try to corner cut more than 1 piece it will pop a little, but you can easily push the pieces back to their place. I highly recommend the MF7S if you want a first 7x7, both for casual solving and beginner 7x7 solvers. It does need some setup to be great, but is absolutely fine as it is.
Overall, I'm impressed with this cube. It does great in the typical metrics: it turns well, it's very stable, there is no popping, there is what corner cutting can be expected from a 7x7x7.
However, there's one caveat: it came with factory lube applied to the pieces (I could feel it on my fingers throughout the first few solves), however there was no lube applied to the core. And this was a problem. I could hear clicking springs and I had the feeling the plastic was getting gouged by the spring / washer.
I used tape to hold all the pieces together and removed each screw / spring / washer one by one. Sure enough, each had plastic "dust" on it from the washer eating at the center piece. However, that's not a design flaw, the cube just needed some lube. I lubed the core and now the cube is fine and very quiet.
So overall, this is an excellent cube, especially for the price. I would just recommend lubing the core before doing any solves. And that can be done in about a half hour by using tape to hold all the pieces together and removing one screw at a time. Be careful with the process; if it falls apart my guess is that it would take at least a day to put it back together.
