Goliath Boomtrix Showdown Kinetic Metal Ball Chain Reaction Stunt Kit - Fun - Educational - STEM, includes Giant ramp tower that can release up to 15 balls at once

Here's the thing with kid toys. The bad ones get used once and stored in a closet then end up in a far away land. It started off as a simple gift for my 6 year old, who loved it by the way after a while there was 4 grown adults laying on the floor bouncing balls all over the place. My 6 year old still plays with it too. Scale of 1 to 10 set up is an 7, still easy enough. Great for anyone that is into science and engineering.

Easy to set up, easy to use. The trampolines are very well made. My 6, 10, and 11 year olds all play and enjoy the challenge. Everyone can get a good go of it, no worries! It is easier than it looks but challenging at the same time!

Assembly instructions are really vague, mostly consisting of a few images of partially assembled pieces. I figured it out, but wouldn't expect a kid to do it. There's enough wobble in the structures that the balls bounce differently each time. I'll adjust a trampoline placement and try again, only to find that he marble goes somewhere different each time. Satisfies when you get a good series of bounces, but it's not repeatable. How much patience does your kid have? This might teach them more or it won't get much use.

Bought this for my 7 year old daughter. She loves it. So did the rest of the family. My 15 year old said “This is the best present I never got” LOL. The whole family was playing it the night after she received it for her birthday.

Bought this as a gift for my 10 year old. He added it to his wish list on his own and it was a great choice and his 5 year old cousin wants one now too.

Box pics make set appear larger than it actually is. Balls don’t bounce near as far as hoped. Disappointed in ball action. Would not recommend. Especially for the high price.

Bought as gift for 10yr old, challenging but great fun

Ordered this for my son as a christmas present. When he opened it the balls were missing, all of the plastic packaging was already ripped open, stickers were used and other peices were missing. Really disappointing.
