Review: Great set for my grandson. - Amazing set bought for my 8 year old grandson. Lots to do and very well made.
Review: This is a great action-reaction toy that will grow with your little one - Bought this starter set+ 2 expansion accessories (a cannon and a spinner) for my 4.5yr old this Christmas - he's loving it- it definitely needs an adult help setup, but it's quite an enjoyable activity to come up with patterns and trajectories together. Just know that this starter pack is actually quite enough - it has a launcher (3 balls at the same time - see video we used two in this example) and a cannon, so the expansion wasn't actually required, although if you do get it, the extra cannon will obviously give you more options). Quality seems quite good, I expected the grey bits to be metal, they are plastic, but not too flimsy, time will tell how long it lasts but seems quite sturdy. PS: box says 8+, probably because it's a bit more complex than the usual simple versions, but I found my 4.5yr old can do quite a bit once I showed him the first few times.
