First off
I bought this because it was on clearance for under $2. I love 2x2s and I am always trying to expand my collection of them. YJ usually has quality cubes and you couldn't beat the price so I purchased it right away. Big mistake. It's on clearance for a reason.
Pros:
Shades are alright
Doesn't pop
Cons:
Hollow pieces give it a cheap feel (you can press in on the pieces and tell that it is cheaply made)
Catches on almost every single turn

For someone like me who averages sub 5 on my main (MGC2) and on this cube I struggle to get sub 7
So buy it if you would like but I strongly recommend you not to.

I have tried to adjust the tension, but the cube will lock up too much when tightened and even then there will still be pops. The cube probably can be adjusted to make it preform well, but i haven't had such luck. When the cube pops, it takes a huge amount of time to reassemble.

Its really average tbh. A great cube for beginners or something to add to your collection but just not as a main.

Out of the box the cube was way to uncontrollable and too loose, i tried tightening the tensions but it didn't help. I was testing corner cutting, and when i tried to corner cut 45 degrees part of the internal mechanism popped. Once I put it back together it was still way too fast. (I went on to receive several pops so I just stopped using this 2x2 altogether).

just do not get this cube. i could be in the middle of a solve and it has a extremity bad internal pops it once happened in my pocket so just don't get it

I got this cube and thought it was the best thing ever created for the first week, after that week it was popping constantly and after a while I even lost a piece, it will pop at least once a solve, and just isn't worth it, not even for beginners.

Peices fly out, sandy, slow stickers chip don't get this

This 2x2 has its cons but there are also pros.

Con: The first con is the turning. While it turns ok, the major set back is it locks up sometimes which can throw you off during solves. Also, the corner cutting and reverse cutting is not great which probably explains the lock up.

This cube isn't completely bad. The great price of 4 dollars makes it great for people on a budget, giving it to a friend, or to have in your collection. Don't except it to be a main, but I would recommend it.

it Really is not good. my solves are 21s on this and 7s on my main 2x2 , the Wittwo V1.

From the video the cubicle made on this cube I was like OH YEAH IM GOING TO BE GETTING SUCH AN AMAZING 2x2 FOR $4. I was completely wrong! There are so many internal pops and catches because not all of the pieces have caps on them! Not a good 2x2. If your looking for a good but cheap 2x2 get the MF2S.
