This is not for speed solving but it is good for beginners.

The YJ GUanshi is an ok 6x6. I just recieved it yesterday and right out of the box... it didn't turn. I first I was kind of disappointed but then I remembered it was only 7 dollars. After I did a couple solves the cube began to turn much better. It is still not finger trick able but I feel if I give it some lube it will turn much better. I am a beginer at big cubes and so far my first impressions are it is hard to make big cubes turn good. Thats it for my review.

When I first unboxed this, it was slow, bumpy and very catchy on all three layers, but the third layer is the worst because its the slowest and the most catchy. Doing OLL parity is very slow and PLL parity is is very catchy. Now there is a popping problem. for example, on my 20 solve, when I was solving the last 2 centers, half of the cube (including internal pieces) exploded right in front of my eyes (at stock tentions). And a couple of the center pieces likes to twist a lot when building the centers, and when that happens then the entire cube locks up, and most of the times pops when it locks up. Overall, this cube is one of the worst options to get if your looking for a new main, the cube is barely speed solvable with all of the catches, lockups, and since its so slow, my fingers feel sore after only one to two solves! I only recommend this to beginners who want to learn how to solve one, if you dont mind it popping often. The only positive about this is it gets a little better with some lubicle silk, and he price are the only positives with this cube.
(DO NOT CHANGE THE STOCK TENTIONS, IT PRETTY MUCH RUINS THE CUBE)

Its great for a beginner 6x6, the turning on each layer is evenly distributed. This is probably because it doesn't turn great. This is alright because I'm not a fast 6x6 solver. Just whatever you do, DO NOT TENSION. This will end up in total destruction as I experienced the day it arrived. And if you a new cuber and/or don't understand the mechanism, trust me you will risk your sanity trying to reassemble this thing. Asides from the negative this is good if you just want to learn and have fun with big cubes and not pay too much. If you fall in this category I'd recommend this cube entirely.

This cube is good for people who are just learning 6x6 like me but is in no way speed solvable. Out of the box it would barely turn and after a little break in it could turn normally but with a little catches. Also, this cube has zero corner cutting and I mean zero. If the cube isn't perfectly aligned it just won't turn. Thats good because you can't those those really bad lockups where all the pieces misalign but it really slows you down. This doesn't mean that the turning is bad, but its hard to start the turn. Overall good for true beginners but for anyone else there are better options.

This was my first 6x6 and it is great. Preformed really well out of the box I put some lube in it after a few solves and now it is even better than before. Overall its a great cube really good for beginners and for its great price.

I imagine this cube is exactly like the YuShi but stickered. The YuShi is an OK cube as it is, but it wasn't named the SuShi. Well, they just released a new 6x6..... and it's not the SuShi.
Maybe one day our fantasies will be fulfilled.
