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.

Great idea, but, difficult to assemble and difficult finding right angles of the trampolines ... because the balls bounce different each time. So, getting it once does not guarantee success two times in a row. The best part is it is teaching my grandson patience and how rewarding it is once you achieve the goal. Also, it is great for adults as well.

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!

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.

Seems nice but it doesn't come with the ball. I know it is an add on but I feel that it should come with atleast 2...

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.

I so wanted to love this game but my kids and us parents grew impatient playing this game. Every time we would place a sphere, it would randomly land in a totally different spot. This due to the cheep plastic assembly that does not handle well the weight of the full metal spheres causing slight movements of parts. The idea is awesome, but I expected great quality for 70 US. Wasn't the case. To make things worse, amazon doesn't back up this product. We have filed for return since Christmas, and we are still waiting from vendor because Amazon will not get involved!

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.

Mein Kind hat sich drauf gefreut.Wo es angekommen ist, hat sie gleich angefangen zu spielen.Zwanzig Minuten später ist es zu mir gekommen und hat geweint .

1. Package doesn’t have all the parts mentioned 2. No instructions 3. Trampoline doesn’t stay at one place after one bounce Overall waste of money.

Great gift for an 8 year old, my son has been playing with it for hours - right up his street and I’d have loved it at that age too. With all the trick shots they see on the internet now, it’s great for them to try things like this, and has much more longevity than flipping a bottle (though admittedly that is a fraction of the price!!)

Great toy for my son it's a easy to put together and my 7 year plays with it a lot,

Box of tut with no actual balls to use the stunt set Very disappointed kids
