Review: Fun and great value for the money! - This element is really cool, and even though it requires a huge height difference, it works extremely well and is 100% reliable if you know how to use it. It is really cool that you can use any number of transfers in your track, making it more flexible to use. I wouldn't recommend buying this element if you don't have either a lot of height tiles or a pro set, because it requires a lot of height and speed to be used. Anyways, it is really good and something I would buy, because it is really fun to watch the marble go from one transfer to the next. I think it deserves a 10/10 if you have enough elements to use it.
Review: Simulates the creative mind! - Great product brought out my son’ creative side!
