2x2: Corner cutting is great! I can get sub 5 seconds easily with it. Not the best in existence, but it is adequate for speed cubers

3x3: Surprisingly good! About as good as a non magnetic 3x3 can get! It comes pretty tight, but after I loosened it I could get under 20 easily. Was not expecting the good quality

4x4: Does bot corner cut very well. That being said, it turns with almost no effort, so if you can turn accurately, it is fine. Can hit 1:30s on it, might be as fast as it can be

5x5: Very smooth! Corner cuts unlike 4x4. Pops are rare, if you treat it with care it will not explode. Big cubes are always going to be unstable, and this one is pretty good.

Overall, AMAZING VALUE FOR YOUR MONEY. For starters, you can’t beat the price. BUY THIS!!!!!!!!!

When I first got it, it was a pretty decent cube box. The 2x2 was smooth and the 3x3 is great but you might need some lube and it does start to break down after maybe a year. The 4x4 was really easy to pop and the 5x5 is a bit slow. I'd say the 2x2 and 3x3 are speed cubes but the others aren't but overall great for beginners of anybody!

i loved it. my old cubes was not very good and strait out of the box these cubes were great. i had a shengshou 2x2 and 3x3 and after lubing these they felt great compared to my other ones. the 4x4 was ok but it couldent cornercut well and the 5x5 was also good.

this got my 3x3 avrage down like 8 seconds and my 2x2 avrage to like 5 seconds.

my only complaint is that it is not magnetic but you cant get every thing.

overall it was great for its price and i would recommend it for people who are getting into speed cubing.

The cubing classroom is a mediocre set.
2 by 2: The 2 by 2 is a nice 2 by 2. The turning is awesome and it is probably the best cube in the box.
3 by 3: The 3 by 3 is ok. It has good turning. It is not the best, but not the worst.
4 by 4: The 4 by 4 sucks. It is just garbage. The turning in the middle layers are awful. My favorite thing to do on it is the edges because the outer layers are ok but the inner layers are complete garbage. The turning is just not fun to do at all.
5 by 5: It is ok. It is way more fun than the 4 by 4.
Basically this box is ok, just beware the 4 by 4.

The 2x2 is great
The 3x3 is good
The 4x4 isn't really that good but if your just starting 4x4 its good
The 5x5 is okay

The 2x2 is amazing with a little tensions and silk, never had a pop and corner cutting is over 45 degrees (mind you with silk and loosening).
The 3x3 is really good but corner cutting isn't even half of 45 degrees.
The 4x4 is seriously my worst 4x4. Its good because it turns fast but it has almost zero corner cutting. Good for beginners though if your just learning.
The 5x5 is okay, it could be better. It isn't my worst 5x5 but it also isn't my best. It's just okay. It was my main for a while since corner cutting is pretty good, and the layers turn pretty well.

my 2x2: poped
my 3x3: is my main
my 4x4: poped
my 5x5: is my only 5x5

Lets start from the smallest to largest.
The 2x2 is a fast cube with great corner cutting, but the pieces break apart pretty easily. I dropped it once and the entire corner that was dropped on exploded and then after I put it back, it was the most vulnerable to explosion.
The 3x3 was the best out of all; I think we all know that the MF3RS is a great budget cube that came pretty fast and after some lube it was pretty good. The corner cutting is good for a budget cube; it does about 45 degrees.
The 4x4 was the worst (for me) because it came pretty stiff out of the box and couldn't corner cut AT ALL. The corner cutting didn't even get 15 degrees which is pretty depressing looking at the other cubes. Inner layer corner cutting was non-existent. I will say it was pretty fast though.
The 5x5 was definitely the second best because it was fast, it could somewhat corner cut and it is really hard to break. The corner cutting did 30 degrees (up to 35 sometimes) and there was 15 degree inner layer corner cuts which is good for a budget cube. It was also pretty fast so that's and added bonus.
In my opinion, the only defects of this are the 2x2 explosions and the 4x4 but for $20 ($18 on Amazon) it is a great bundle.

Title pretty well says it all. The cubes aren't amazing but they are great for each size and learning how to solve it. Once you become more proficient then you'll want to look into upgrading if you want to take it to the next level. If you're casual about solving though, this is a great set!

I think this set of puzzles is great for starters! the cubes are pretty durable and have lasted me a long time. These were the first 4x4 and 5x5 I ever got and while they aren't anywhere close to being superfast speed cubes, they are great for people who are looking to branch out from the 3x3. At present these cubes are set up and perform ok. but out of the box, these puzzles arent the best. So if you dont mind setting these cubes up, you can get some distance with them. But, these cubes are probably only good for peole who are just getting into cubes.
