Gear Building Toy Set - Interlocking Learning Blocks - Motorized Spinning Gears - 81 Piece Playground Edition by Krazy Gears

Nice product. But too much of cost.

Los engranes son mas pequeños de como lo esperaba y puedes armar el juego de diferentes formas, según hagas el acomodo de las piezas, pero es frágil, o sea, con cualquier movimiento se desarma, recomiendo tenerlo en un lugar fijo mientras se usa.

The media could not be loaded.  These things are amazing!! And the price is fantastic. Are they perfect, no, ours had a couple of broken pieces and the plastic could be a little thicker. Oh well, they work, and they're VERY affordable! You can't have it all! We have 4 sets now and we absolutely love them! Fyi, pic and video shown uses 2 or 3 sets.

Do NOT buy it! Terrible quality, only worth 5 dollar!

My sons Occupational Therpaist brought this over to test some skills. Each time he cried because he loved it that much, especially when the gears make the other gears spin. He is obsessed with all things that spin. Anywho I bought one and it came the next day. His precious face when he say what it actually was. I think that was 2 days ago ----- he is now playing independently lol

These are a lot of fun. My 4 year old and the kiddos I work with love them. It operates with batteries and you can build them flat or up. They do feel a little cheap but if your kiddos take care of there toys I recommend
