Query: Poorly Made.

I bought this item for a 7 yr. old on her birthday. She loved it and it worked well...for a little while. Within a week's time, a tooth on one of the gears that actuate the dynamo, broke clean off. I have opened it up in hopes of a repair, but it seems I'm out of luck without a replacement part for the gear. I could envision using this flashlight in emergencies, but for sustained use, it seems useless. I am disappointed mostly because this item has potential to be a great educational tool to teach children about electronics and electricity while still offering some practicality. Unfortunately, this item does not have a durable design to be useful to kids.
