Review: High quality, well designed, incredibly engaging for kids! - I would consider myself as a strict grader of products. I am not easily impressed and usually expect a lot from anybody selling me anything - especially for my 6-year old. So please realize that when I say I absolutely LOVED this product, they must have done a lot of things well. Quality: The finish of the laser-cut parts is amazing. Everything in this complex mechanism fit perfectly. Design: Someone at Smartivity's really thought through this design and assembly. It's a thing of beauty and works flawlessly in the end. All fastening is with non-messy rubber bands. The directions are easy, and even my 6-year old followed the instructions effortlessly. Engaging: My hyperactive daughter stayed put for the entire time and was in a total state of flow in putting this assembly together. We collaborated on building it as a father-daughter team, and I have to say that I was totally into it too. The best use of the time and money we've invested in a build it yourself toy in a long LONG time!

Good Quality. Quite engaging. Only if the track size of roller was a bit bigger.

### ⭐⭐⭐⭐⭐ Wonderful product, Superb work by Smartivity
*by P***R on 2 May 2022*

Amazing ideation by smartivity, I am so amazed to see this creativity with the product. While opening the package it looks like a daunting task however their instructions are very sequential and clear, allowing no confusion no misses. Very high quality product with very precise cuts for separating each part. Hats-off to the thoughtfulness here by the product makers. I ordered this with only one thought that, this will take my 3year old toddler away from you-tube and at least the start was good. thanks for this interesting and intelligent product. Only one note: i am going to use it as an engager for my toddler 3years old, I doubt whether it would be an interesting item for the age mentioned in this product (8+yrs) - as kids of this age might not really feel this product amazing after few days
