Light Quality: Good! Ease of Cranking to Power LIght: Easy!Best Feature: It's waterproof!! Worst Feature: bulky to hold in your hand. Confusion Factor: Box that it is packaged in says it is a Dynamo flighlight w/ Mobile Phone Charger...but there is no place to plug in a cell phone! (This feature was not mentioned in the Amazon listing)Overall: Prefer my other flightlight, a Viatek Dynabrite Flashlight.
