We found the best review of the BoGo solar flashlight at the LEDMuseum.org, where battery life is tested and the flashlight is run through durability tests. We found other hands-on reviews at Kevin Kelly's Cool Tools and at GreenDealsDaily.com, which includes a video. Articles at Vision Magazine, The New York Times and Time magazine provide convincing details about the importance of the BoGo Light donations to refugee camps and Third World villagers.
Reviews recommend this six-LED solar flashlight as the best rechargeable flashlight for household use and disaster preparation. It comes with a hook for hanging, and a "Night Glow" strip makes it easy to find in the dark. "BoGo" stands for "buy one, give one" - for every purchase, a BoGo solar flashlight is donated either to a serviceman in Iraq or Afghanistan, or to a villager in a developing country. Eight hours of sunlight recharges the three AAA NiMH batteries enough for four or five hours of reading light. The newer SuperBoGo Light (*est. $30) is still being refined, but includes many technical improvements, plus three extra LEDs for lighting a whole room.
This well-illustrated review includes results of a battery-discharge test, showing the solar-charged batteries run about six hours at full level, then fade to about 10 percent at 11 hours but only if charged in direct sunlight. The flashlight proves water-resistant, but not waterproof if submerged.
Review: The Punishment Zone: Bo Go Light Flashlight, Craig Johnson, Oct. 2007
This brief review gives the BoGo solar flashlight top ratings for value and quality, with slightly lower ratings for environmental-friendliness perhaps because it doesn't use lithium-ion batteries. The brief text is accompanied by a video that says it provides "a decent amount of light" with a seven-hour runtime.

This reviewer likes to hang the BoGo solar flashlight over the bed for reading at night, saying it's plenty bright enough. The review also notes that you can use the solar panel to charge an extra set of batteries to extend runtime or to use with another device.
