I love the design aesthetic. Packaging is great, with it being easy to remove and repack as needed. It has a solid feel to it, is easy to get batteries in and turn the unit on. The actual operation of the dynamo is fairly rough. the fixed drive area operates inconsistently, with a lot of starting and stopping. This might be due to belt tension or something else. I'll tinker around with it and see if I can get it to smooth out. I love the concept, though, and look forward to lubing up some car axles and breaking them in on this.
It is a fun thing to mess with. The cars are a little fiddlie to get lined up right and then they still seem to jump around more than I'd like. All in all I enjoy it.
