I've used this light for a few weeks now and I am very impressed. It charges quickly and the multiple output levels are quite useful in extending the run-time.

Although I know it shouldn't be submerged; I've noticed that when I left it out on my deck to charge, that a rainstorm had no effect on it.

I plan to order additional units for gifts, as this seems to be a great light and produced to enhance those where no electric is available.
