I really, really love this flashlight. It is so durable, yet light-weight and easy to grip and carry. The solar charger is handy when I'm away from a power source to recharge it and seems to last forever when fully charged (although the package indicates it lasts *only* 50 hours on single full charge). I bought several for Christmas gifts for my family, both with the black case and the bright yellow case. There are no batteries to replace, it's water-proof, floats in case it's dropped in a stream or other water source, and the light is very bright. This is my go-to flashlight and I just may have to order more as gifts for friends. BTW, the Customer Service of this company is fantastic!!
