This was my first time trying an off brand so I was very skeptical going in and extremely pleased with the piece quality and model design. Box arrived in good condition, no missing pieces. To address the reader's concerns:Piece quality:The majority of the pieces are indistinguishable from Lego brand without getting out your microscope and looking for the brand stamp. Only the pins and beams have visibly different designs, but are functionally up to the Lego standard. The catch, perhaps, is a higher tolerance for connections, meaning that in this lot of 50 or so black pins, one or two are slightly looser than normal, and one or two are slightly too firm.Set design:The hex walker robot is a fascinating mechanism that really works, albeit fairly slowly and weakly. The other two models are more robust, though much simpler, and really just serve as inspiration for connecting the power block to your own creations. Can't think of any Lego set that gives you this much utility per piece.Downsides:Assembly is lacking many features taken for granted in Lego sets. Bags of pieces aren't organized in assembly order. Internal parts aren't color-coded (everything is grey) which makes finding the right part hard (I thought a few times that I had been shorted a piece). No bill of materials in the instruction booklet. Power block has limited functionality: one speed, no servomotor, cannot edit mapping to controller keys.I bought this when it was marked down to $40 but even at $50 it has better price per piece and utility per price than anything Lego is offering these days. Highly recommend.

The box was damaged slightly upon arrival, so my first task was to get everything out and see if it was still going to work. It did. Lights up and remote seemed to be working. Having said that, I have yet to finish piecing this together. I was going to put it together and surprise my son with it, but I found I no longer have the patience for construction sets that I used to. The instructions are clear and much like the ones you get when purchasing major brand brick building sets. The concept is really awesome, but I wish I had waited and let my child do this activity, as he loves stuff like this. I literally made it 10 minutes before deciding maybe he should be the one to do this. So far, it appears to be exactly as described, but will update if that status changes. Also will update when this project is completed. Despite it being unfinished, it still, in my opinion, deserves a 5 star. You can tell it is pretty good quality before you even have it fully together. Bricks stick together firmly, easy to follow instructions, and definitely get the excited feeling of the possibilities of trying all 3 designs you can build with the one set. I am just going to let my son finish them all LOL. The reason I gave only 4 stars, is because if you are going to purchase as a gift, I know I would be upset about damage to the box. Even not purchasing as a gift that was going to be staying in box before given, I was slightly upset about it. Disheartened that I discovered my childhood passion is no longer a passion, but happy I have passed that passion to my child. He will truly enjoy this!

Divino me encanta , tiene tres maneras de armar , muy bueno para mantener a sus hijos entretenidos y además para la motricidad . Lo recomiendo .

As we assembled this small robot in various ways, charged him up, and watched him move, we were blissfully unconscious of the passing of time. The construction of this robot wasn't as challenging as our more involved programmed robot creations, but the parts held together better and didn't stress out or frustrate my son as much. It was very enjoyable. Over the course of the following several days, he discovered more ways to put him together than those suggested by the box and discovered how to get him to push objects about the room, like a ball to our dog. NOW THAT was funny! Our dog wasn't sure what to think.

This is a great gift for kids who like to build, construct, and problem solved. If you have any grade school age, kids who have been in the steam program this is right up their alley.

It requires them to use that all of their problem-solving skills following directions, and building to create a fun little robot.
