I bought 3 of these for my grandson's they spend hours playing with it. The stickers aren't as sticky as I'd like so I used tape too. But apart from that even the adults love it. Excellent product for kids and adults too 😆

I bought this for my kids to paly with on rainy days! I'm so shocked that it sticks to everything ! You could literally take this on the train and keep your little ones entertained on the longest of journeys ! It even sticks to textured wallpaper, which only proves the quality, had this product for a while now and it's very robust. I have 5 children and apart from losing the odd piece what we do have is still in excellent working condition ! Very well made, and a fantastic product ! Thank you :)

Only tried it on our window so far, but love it. Some review caution about the stick, but not a problem for us yet. I’m guessing it works better on some surfaces than others. We’ve repositioned again & again on window & no problems at all with the stick. When you open the box, it’s best to have an adult attach the nano-suction pads. After about 10 minute prep, you’re ready to go! We got this toy on sale and I’m thrilled with it. It was perfect to get my 9 yr old off electronics & into creative play on a boring snow day home from school. He refused to read instructions, but figured out most of the pieces/assembly on his own. We’ll have to explore the few levers/mystery pieces this weekend!

This is a favorite now, for grandsons ages 6 & 8. They love marble works, and this presented an additional challenge. I worried they might not stick - they actually stick to a window very well. I wondered if the marbles could damage the window- not a chance. They played for hours. I ordered some additional sets the following day for the next time they come. A little challenging for the six year old at first, but big brother helped. I highly recommend this set - and I think it’s best to get at least one ‘add-on’ set.

My Son loves these and sticks them on his window for a marble run!
