A lot of fun.
I actually bought this for my grandkids, but as this was my first Unicorn purchase I thought I'd test it out myself. I was pleasantly surprised by the quality of the product, and the manual was very easy to follow. But be aware that it is about 80 pages long and there are a lot of parts, so if you're thinking this is a half hour quick kit, it is not. Having said that, the finished product works well and is a lot fun to play with.

A piece broke and emailed and NO RESPONSE
A piece broke while removing from the sprue in the parts tree. To be clear this was my fault. I emailed asking to pay for the new part but they never even sent a response back. The product appears well made but I am leaving them one star for the lack of response.

Crane arm
The crane arm which opens and closes it is not strong enough, but everything else is ok!
