Tools and Hardware Reviews of the Shake Flashlight- No Batteries- Simply Shake to Recharge
Tool Review: Reed switch doesn't work, the flashlight is inoperable.
Summary: 1 Stars
I am helping my son with an electromagnetic induction science fair project and have studied extensively the requirements for these types of flashlights to operate. This flashlight is better than the 'fake' shake flashlight we'd previously ordered for $2.35 at amazon.com, because it actually uses a real NIB magnet and appropriate circuitry. However, the reed switch (which uses a small magnet to connect the capacitor's stored potential to the LED)doesn't work. Thus, the LED won't light. I'm very disappointed with this purchase. There are genuienly amazing shake flashlights that, both in function and design are truly brilliant devices, but they cost a lot more than this flashlight, so it seems that the old saying, "you get what you pay for", is proven true, once again.
