    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    Small

    Needs no battery to play

    Good for a demo for solar power and energy

    Easy to use and play

    Come with a nice transparent plastic box (so it won't run away by itself under the light, :-P )

    Faster than I expected when under enough light

    Cons:

    Don't put it unattended and out of box. It may go away by it self with strong enough light, and you may lose it.

    OtherThoughts:

    The solar cell need to be in a very large angle (70 degrees or more) to the sun to get enough light. In the winter (which has the smallest angle of the sun to the level ground), it may not work on ground without extra light.

    This is not a problem of the car. This is because Winter is Winter, and Canada is in the north.

    Bottomline:

    It will certainly work better in summer, with more sunlight.
