Features list indicates many features that this item does not come with. "Emergency Whistle": The unit I received does not have one. "Easy-to-press-on-off button": The unit I received must be twisted to turn on/off, steady/flash mode. "Detachable Lanyard": not included. No docs were provided on Lite Gear's lifetime replacement program. My glow stick has an 1 hour auto off feature and no way to disable it. Overall, the product I received does not match the description as listed. Perhaps the model has changed since it was made available. The $2.99 price = you get what you pay for.
Pros: Inexpensive, novelty
Cons: 1 hour auto off
