3x3x3 Brain Teaser Magic Cube IQ Puzzle

Pros: It's a good cube. Cut corners well. It needs no lube. Mine is REALLY fast and I still haven't lubed it. I have been using it for 2 weeks and it have never popped.
If you are a good cuber, you will get a good speed with it.

Cons: It's not really a con but... i don't like white stickers in a white cube. I replaced it with a black set.
Everything else is OK.

Other: When you receive it, just play with it until you find it turns smooth.

Pros: Just so there is no confusion, this is an authentic Dayan III LingYun V2 speed cube, the 'sequel' to the very popular Dayan GuHong. Also, it is Version 2 of the LingYun, which means that it comes with torpedoes installed.
To the uninitiated, 'torpedoes' are small pegs of plastic installed inside the edge pieces which makes the cube almost impossible to 'pop' apart when twisting frantically.
It comes fully assembled in the original factory box, but without the Dayan 'member's card'.

Cons: This is a FAST cube, and came pre-lubed. THe factory did a fair job of setting the tensioning, but you may need to adjust the cube a little to fit your needs. For me, it is almost perfect.
Also, while the core was lubed, the springs under the screws were not, so the cube is a little squeaky while turning some sides. Lubix or silicone spray UNDER the lip of the center screws will completely eliminate the noise.

Other: This is the real deal, and anyone who likes the GuHong, or is interested in using a real-deal speed cube should pick one up.

Pros: This is a DaYan Guhong, which is widely regarded as the best speedcube on the market. It cuts corners excellently, and is extremely smooth.
The cube is fully assembled and fully stickered, which is always good.

Cons: Some tweaking may be needed to find the perfect tension, but that is to be expected with any cube.

Other: The best speed cube on the market at an excellent price-a must buy

Pros: Very good cube. good rotation Don't pop (depends on screw setting) Ready to use (already make, not a DIY) internal system (very good)

Cons: Poor label quality (you can see a circle by transparency)

Other: A cube for all people from beginner to expert. I'm fall in love of this cube ! very amazing . It's my 3rd cube 3x3x3 and i can't come back to my old one's.

Pros: - Very fast cube - No pops - Installed torpedoes - Good tension (adjustable) - Cheap

Cons: I don't really have cons, it's almost perfect cube. For someone it could be too loud, but i like that sound, but it could be lubed to make it quiter.

Other: It's a genuine DaYan3 Ling-Yun 3x3x3 Cube. Must have!

Pros: Much better than those low-quality $2 cubes. Good sticker quality, good plastic quality, well lubed. Really good for speed cubing, and even good if you are just getting started.

Cons: You must be careful while turning 2 sides at the same time because pieces may pop (and it's pretty hard to put them back if you don't remember where they belong to).

Other: Awesome, will buy again soon.
