My son loves the sound effects but the weight makes placement important. The lower the better.

I bought this as an extra for my Mindware marble set. It connects well and so far works great. Makes a fun addition to my set!

I bought these for my grandson for Christmas. He loves them.

These were a big hit with the kids. They work well. Not sure if they really add all that much to the marble run experience, though. They are definitely not a mandatory part of a good marble run.

Although this product is going to be a Christmas gift for my 3 year old grandson, I am positive he is going to love the noise factor. When I say noise, do not think of a continuous irritating noise. It reminds me of the days of real pinball machines and the noises those machines made. The product is quality, not those cheap flimsy plastic marble track products. I was so happy to see this product is durable. Side note: there is a switch you can move to shut down the noise.

Kids love this item!!!

My son has multiple building sets and their additions so we were pleasantly surprised to see them release something that he does not already have some variation of! You actually get two in each box and they fit perfectly with the rest of the Marble genius pieces. I was worried about the sound being a bit obnoxious but honestly it is a short cute sound that isn't too drawn out or loud. I would buy the others but they are currently sold out so I will be keeping watch for them. The only thing I am unsure of is battery life but if it dies quickly I will update

First of all they are Not too loud which as a parent is important! Second the sounds are interesting, fun and short. It even works really well when a ton of marbles go through at the same time. These are a great addition!!
