Honestly, REGRET it. It doesn't worth the price, doesn't worth even $5.

I like this cube. But with that it does have a lot of issues, at least ones I've noticed. First off the feel is nice, it's very smooth and a little slow out of the box. I got it in white and it looks amazing. Sadly that's about it as far as it being good. Where do I begin, it has literally no corner cutting what so ever no matter the tensions (I understand it's a 6x6 but my Qiyi Wuji 7x7 out performs and cornercuts it). If the tensions are tight it gets caught and hard to turn, if they are even slightly looser, God awful lock up's/pops. You cannot get the tensions just right, it's either some of the worst pops and lockups or it's so tight you can barley get through a solve. I've never had any other 6x6 to compare but this isn't a reliable cube in my opinion. I hate to be leaving a bad review on a cube I want to love so much, but I can't deny the problems it has.

mine was a bit sluggish out of the box but i wiped it out and put some silk in it and it is just amazing it is better than my friends yuxin red

Since I started cubing, I've liked 6x6 in theory, but not found hardware good enough for me to like it in practice. The WeiShi GTS finally did it for me! I've used the QiYi WuHua and the ShengShou (modded with Dayan Springs). I haven't tried the Yuxin Red, so I can't compare them. The WeiShi GTS is more stable and faster than the QiYi WuHua, and is more consistent across the different layers. The WuHua has excellent outer and middle layers, but a super-sluggish middle layer. This WeiShi GTS has very fast outer layers (for a 6x6, don't expect it to be like a smaller cube), slightly slower second layers, and slightly slower, but still smooth and easy middle layers. It can get those annoying lockups that every 6x6 is prone to, but they usually aren't too bad and are quite rare on my medium tensions. It also has a nice rounded feel that I enjoy. The only downside for me is I wish it were smaller. The WuHua is still a great cube, and some might prefer it due to it's smaller size, flexibility, and a feel more in line with other cubes in the QiYi Wu- line, but for me, I like the WeiShi GTS more in almost every way (except size). For set-up I broke it in with about 20 solves, then loosened it a quarter to a half turn on each side (tensions seemed mostly even), and lubed with weight 1 and Maru.

This cube is okay and everything. The only thing I don't like about this cube is that when I try to speed-solve on this cube, it usually pops. I expected the corner-cutting of this to be better. Overall, it is OKAY.

I bought the stickerless. Its a little more pale (less vibrant, I guess?) Than I thought it would be. But it doesn't seem to want to pop, even if im a little mean to it. I don't speed solve but will move it quickly when I start warming up. Its very forgiving. I would recommend this cube, but a stickered version.

This cube is fantastic. This cube performed better than my spring swapped, well broken-in, yuxin red 6x6 after the first solve. This cube is unbelievably stable and smooth.
With a bit of lubricant this cube is by far the best 6x6 on the market and it didn't require half the work the stupid yuxin needed.

When i first got this out of the box, it felt sandy and was a bit sluggish on the 3rd layers. After a bit of breaking in, I dropped DNM-37 on all layers and broke in. Now after about 50 solves this cube is fast and stable. Highly recommended!

Not the best 6x6 I have seen from moyu, even when I drop a bit of DNM in it, it is still sluggish in my opinion, bit it is still better than the ShengShou 6x6

WeiShi GTS is a very stable and smooth cube but there are 2 problems: firstly it is big, secondly, it's slow and feels tight. I had a KungFu CangFeng 4x4 that I never use, so I swapped the springs with the WeiShi and tightened my WeiShi to an extent where the furthest you can pull the 2 middle layers apart is about 5mm. That took care of the second problem.

The spring-swapped WeiShi is one of the smoothest cubes in my collection, and it is as fast as some of my 5x5s, including an MF5S and a Magnetic WeiChuang. The stability is still among the best I have seen, and the outer layers can corner cut 1.2 pieces forward and 0.7 pieces reverse. Compared to other 6x6s the WeiShi is also the most immune to cube defects such as pops and the deforming lockup. Even if I try to force it, these defects do not happen to my current setting. The only negative thing about the WeiShi is the size.
