    It was a Christmas gift for my grandson and he loved it!

    The media could not be loaded.

     I got this set to build with my 8 year old. He built it mostly on his own. The instructions were pretty clear until the last few steps.

    The pegs were hard to push together in some areas and incredibly loose in other areas. This led to some pieces being very loose and woogity and working out of line as the machine ran. Easily pushed back into place though.

    For the most part, the set was a cute set and easy to build. The solar panel didn’t power the machine at all. The battery hookup was one of the woogity areas and wanted to fall apart, but did power the machine well.

    For the most part it was easy to build and fun to use. I would still recommend it even though the solar is a no go and it’s a little woogity in some spots.

    Got this for my Hubby & he loved putting it together. Didn”t take him no time at all… 🙂

    This is a really fun machine IF you can manage your way to assemble it. There are only a few written instructions, the majority are just pictures, many of them inaccurate. The parts diagram showed circles as ovals and had mislabeled parts. We had to guess at how it went together, had to take it apart once, but managed to build the thing. We chose to use the battery option and it really is fun to watch. I built this with my 9 year old grand daughter and 5 year old grand son. They were so proud of themselves for building such a neat machine! It says no glue needed, but if I had it to do again, I would glue everything except the gears, which need to turn. It’s quite fragile in the unglued state. It was A HUGE and frustrating challenge to build, but very enjoyable once it was done.

    Smaller than I thought it would be

    My 12 year old put this together in about an hour and then tinkered with the solar and battery options etc for another hour. She loved it and it worked as expected. It was very satisfying to be able to complete a project like this in one afternoon. She’s done a few of these now and I can say that this one worked on the first try and the pieces were sturdy/ not easily broken during assebly.

     The qualityis great and the engineering is beautiful.
    ‘Course I just HAD to load it up with balls.

    One thing…if you have a problem with the ball hanging up at the bottom re-entry, just raise the ramp a little
    Never cut or trim…you’ll mess up.
