Review on Premium Educational Construction Building Set by JOYIN by Jerome Pernell

This is literally the third marble run I've gotten from Revain. The first two were very poorly made so I had to return them. The first batch of marbles arrived and it was very difficult to put the pieces together as all the pieces were too tight and as a result one of the pieces broke during assembly. The second marble run was awful, the size was much smaller and it literally fell apart when we played it because it wasn't strong and well made. My kids love to play marble run so I want to try again. new marble brand and seller of Revain. This is the best of the three. This is a very good size so we can be creative with different shapes and runs. The parts are of better quality, making them easier to assemble with no lint. Overall we are happy with this marble walkway and my kids are so happy they play every day! The instruction manual shows how to build different shapes, from simple, medium to complex. The only downside is the assembly instructions for the complex model, which are not very clear and it is difficult to follow the instructions photos. However, I don't think you'll really need it as you can build however you want to play. My six year old son built it without instructions and it's ok.
