Fun!

Bought this, along with the Starter Set, the Super Set, and several sets of accessories, for myself. Yes, I'm an adult. Yes, this thing is fun! Everything in this booster set works as described, except sometimes the tracks with the rails can be finicky. Occasionally a marble will get stuck or will fall off. The other pieces work great. I actually went back and ordered a second booster set in order to get two more of the "splitters". They come in very handy. The spinning wheels and the jump piece are particularly fun.

great fun for everyone!

My grandson LOVES this marble run add-on! He already has one of these (from Christmas) so I bought him more pieces for his birthday in January. He and his sister ~ AND their parents, LOL ~ have a great time setting up the various tracks, changing them every time & watching the marbles run through! I plan to order more in the future for my son's children ~ I'm sure they will love it also. :)

I bought 3 sets of these for MYSELF! I have 5 grand children and eventually I will allow them to play with them, but for now they are only for me and I'm 69 years old.

fun new pieces!

This is a great addition to our set. We love Marble Genius! This set has pieces that aren't included in any of the other sets. My kids particularly love the yellow, wishbone shaped ones that split the marbles down two tracks. The pieces are well engineered, which I was nervous about at first because the tops look really short but it really holds together well! Something else that sets Marble Genius apart is the transparent pieces. It's fun to be able to watch the pieces through all the twists and turns.

Well-designed and robust

This set contains some intriguing new pieces, and a lot of thought has obviously gone into designing them. They hold together firmly, yet are easy to join and unjoin. Every piece is strongly built, even the skeletal curved chutes, which are considerably more robust than they look. Marble size is important with these particular chutes - too big or too small and the marbles wilI jam, just right and they work beautifully. I took a chance in purchasing this set, as we had no Marble Genius pieces, just a mixture of pieces by Marbulous, Marbutopia and the ancient brand of Broadlands. I was pleased to find that the new pieces fitted reasonably well with all the other pieces, if not quite as snugly as they fit each other. I'm impressed with the quality of this set, and am tempted to purchase more from Marble Genius.

Good add on

Such a fun product that encourages problem solving and multidimensional thinking. My son and I have a good time constantly trying to find the most complex structures to set up with this.

Great additions.

These pieces are a great addition to our existing marble maze set. The spliters are fun provide more path ways. The jump is fun, the large red base is great for collecting the marbles at the bottom as well as providing the always needed stability to the tower.

We love these!

My 5 year old son loves his new marble track. He says it's "so cool". The pieces fit together well and are well made. He has had them for a month and has played with them every day, they're still like new. I highly recommend this product!

Roller coaster!

Marble tracks with these look like roller coasters and interest any kid! Physics at it's funniest!
