Cuberspeed Carbon Fiber Sticker Speed Cube Stickerless with Black Sticker Puzzle 3x3x3 Original Speed Cube (4x4 Carbon Fiber)

Absolutely amazing. It turns really smoothly, and corner cutting is good. The stickers are placed somewhat askew, but you can't really tell unless you look closely. It's durable, lightweight, fast, and feels really nice. Perhaps a little loud, but not clunky at all. A perfectly solid 8/10.

The quality of this speed cube is so much better than the common brand. My son has this type of cube in several different sizes/shapes. Won’t buy anything else.

The GuanSu is the newest 4x4 model from YJ, a company known for great budget speedcubes, including the very popular Sulong 3x3. I heard that this puzzle uses a mechanism somewhat similar to the Aosu but has some tweaks to make it less expensive.The first thing I noticed about this puzzle out of the box is the speed of the outer layers. They are nice and quick, even on tight tensions, but the inner layers are a bit slower until after about 50 solves. Also this cube has very hard plastic, which makes it feel unpleasant to some. I, however, really enjoy the feel. Also, the cube arrives on extremely tight tensions so it is advisable to pop out a few center pieces and loosen the screw on each side.The GuanSu also has a pretty nice turning feel to it. Sort of light and a little blocky but smooth. It's not quite as nice a feel as the AoSu's buttery and crispy feel, but it's still great for its price. The stickers are the standard YJ/MoYu shades and applied very well. One complaint with this puzzle is that it seemed to catch a lot. My AoSu catches to but it will cut corners a little better, so you can sometimes just muscle through the catches. When the GuanSu catches it stops you dead in tracks and you have to clean up the alignment of the puzzle to get through it. I tried messing with the tensions a bit to alleviate this because they were really tight from the factory. Just a quarter turn on each screw improved it somewhat but the catches are still there every now and then.At the end of the day I got this puzzle for $8 and I think it is an amazing cube for that price. In some aspects it is on par with the nearly $30 AoSu, but has a few tradeoffs. I used this 4x4 at competition and got 2nd place. Overall, this cube did arrive 2 weeks before the projected time and is amazing for its price.

My daughter is a huge fan of cubes but has always learned them pretty easily. This one was harder to learn and more of a challenge for her. The cube moves swiftly and smoothly.

Delivery was fast, efficient, and product is in great condition.

I really enjoy the aesthetic of this cube. In fact the colors are actually easier on my eyes, I thought it would mess me up.

The stickers stay on quite well. I take my cube with me everywhere

Very soft, my son loved it

Bom produto de ótima qualidade. Adorei!
