This is an excellent toy. My son saw this at a friend's house and we decided to purchase it for Christmas. It fosters creativity and visual/spatial skills. As with other Haba toys we have, it is a work of art - form and function.

This is the first HABA toy my son received for Christmas. It has kept his attention and he loves to make the bell ring. The variety of blocks makes many great runs. I have a feeling that this toy will be one that actually holds his attention. Right now we have to make the runs and he rolls the marbles, but already I can see his little analytical mind trying to figure out how the whole thing works. We look forward to adding pieces to this set. The quality of the blocks is excellent and better than anticipated.

This is another wonderful toy from Haba! The solid wood blocks are smoothly sanded and feel nice. The idea of this toy really makes children think. We got this for our 3 1/2 year old Godson for Christmas and he really likes it. I was disappointed that the instruction manual was ONLY in German. You don't need the instructions to have fun with it, but there were some neat additional suggestions of games that I muddled through after not speaking German for years. I would be nice to have an English version. The one thing that would make this toy better would be if the pieces locked together somehow. The blocks stack, but do not lock, so if it gets bumped, it gets pushed out of alignment or falls. Over all I am very pleased with the toy!

Our son was thrilled to receive this, and the first thing he does every morning is head straight for his marble track. He loves to problem-solve and is very proud of his finished runs. Admittedly, the more sophisticated configurations need some adult guidance, but it's so much fun the effort is well worth it. We have not exhausted the possibilities yet, and I'm not sure we could if we tried! Fun, fun, fun.

We got this about a year ago for my now 3 1/2 yo son. He loves it! There are endless ways you can put it together and he loves to try different things. My 1 yo daughter uses the blocks without the marbles and also has a ton of fun. I love that we can buy accessories for it every year to add to the fun!
