We absolutely love our GE 3-in-1 power failure, flash light, night lights. Our entire extended family has discovered them and we use them EVERYWHERE! They are in our homes in various places, in our RVs, and we even have them in our suit cases for hotel stays. The grandkids feel secure all night long. They truly are super bright as night lights. We especially love that they are readily available as bright flash lights. Just detach from the outlet, fold up the prongs and you have a rechargeable flashlight that lasts for hours. They ARE wonderful as light-sensing night lights and without fail they always come on when the power goes off or when they are removed from the outlet. I can't imagine why another reviewer said they don't stay on when the power is off. We never leave home without ours. I don't usually write reviews, but due to the negative reviews that others have posted I felt that I must. These are a great product and I hope that GE will continue to make them!
