I wouldn’t recommend these for the price, they are super expensive and the magnets are extremely weak. My son seen these at the children’s museum in Phoenix and loved them so we ordered a set for home, you can’t turn them at all as they just all slide down even when not turning them the weight of them makes them just slide and fall, it’s been to long so can’t return them, he literally just lays them on the floor and spins them that way. The ones we initially seen had very strong industrial magnets on the back these are just flimsy.

These are nice, sturdy gears. Just need a big area to use. The double sided white board/magnetic board with the bottom tray will only work with a few gears.

Love the smaller magnetic gears so had to add these. Expensive, but not too bad when on sale.

We absolutely love these in my Home Daycare. From the 9 month old all the way up they love turning them. They pretend they are steering wheels and more. And the magnets are very very strong so they really stick!! I highly recommend!!!

Kids of all ages love playing with these giant gears on our magnetic activity wall! I paired them with the small gear set and they can't keep away from it. So much fun, a unique product and very sturdy and high quality. Love it 5/5

These are large, sturdy gears. Only the red ones have handles, but they are turn well without them. They stick to my son's white board really well and are easy to turn. They are easy to fit the gear spokes together. Really happy with our purchase.

Big Gears! We loved them~ very colorful and heavy duty.

Our toddlers absolutely love this, it is large enough so multiple kids can play and interact.

Although the children like the product and is engaging it doesn't stay together as it constantly slides, the magnets need to be stronger. it is definitely not worth the money. The quality is good but for $140 The children lose interest when it slides down the bored and they had to keep putting it back together, it makes one or two turns maybe three before it moves
