So this comes with a black cube and a white cube, and two packages of lego-like pieces that attach. There are 10 pieces per size, so one extra in case you lose one. The pieces look and feel just like real legos except they lack the little "lego" word embossed on the bumps. Since there is a black cube and a white cube, the bags of lego pieces are slightly different. One bag has black square pieces and the other bag has white square pieces for one of the sides. I tried attaching some official lego pieces to the cube to see how compatible they are and they fit just fine.The cubes turn nicely and easily. I like the feel of playing with them with the little lego bumps on them. My son likes them a lot. I hadn't realized that they were adjustable until he accidentally detached one of the sides. I've got a picture of that here. So the center piece of each side has a lid that can get popped off with some effort. Underneath that is a screw threaded through a spring to attach the piece to the center of the mechanism. My son managed to spin one of the sides enough that it unscrewed the center piece somehow. The result makes it looks like the cube is broken, but it's not. You need to pop the cover off the top so you can access the screw, then screw the piece back on. How tightly you screw it in to press on the spring changes the tension on the cube and how easily the side turns.Overall, I think these cubes are pretty good. An original take on the regular old Rubik's cube. Fairly high quality construction.

So fun!! They can assemble and disassemble these cubes. Or assemble and solve. It's fun because they can make them however they want!They operate smoothly as well, no sticking. Pretty solid and sturdy.

Comes with it's own set of colors to set up a basic cube. Doesn't spin as quickly as a speed cube, but better than on original rubix. I've yet to pull out my personal legos and make a wicked custom cube, but when I do... The possibilities will be endless. I'm not quite sure what we'd need 2 for besides buying several for a gift bag or whatnot. I keep one at my desk, the other is on the coffee table for anyone to take a stab at.

I ordered this for my son (5) for Christmas, but let him have it early. He loves legos and has recently become obsessed with Rubicks Cubes so I got him this. It has 2, a white and a black cute, and 2 packs of Lego fronts to create your own. It’s very easy to put together and play with. If you get too stuck, take off the legos and start over. Hours of fun

So these are pretty cool. I got them for my boys for Christmas. There is a black and a white cube. They both come with their own set of colored lego parts to put on them. They seem very sturdy and I can't wait to see what my boys will come up with in their imaginations when they put them together. You can do so much with them. Rubics cube or your own design of whatever. Great gift for lego lovers!

Great, great, great! Slightly smaller than the original 3x3 cube, but easier to hold and much more easy to manipulate. Very happy with this speed cube!

My boys love to fidget around with rubix cubes and these are such a fun update to this classic puzzle toy. The building block surface is totally compatible with the LEGO brand. My children are ages 5 and 11, and boy enjoy this toy immensely. They are sturdy and well made. They twist around easily and have held up perfectly over the past several weeks of heavy use!

Lots of fun. It is a great gift for the beginner or the novice. Very durable and sturdy. I would definitely a great value.
