The instructions are good and the switches to activate the studying gentle and set the lighting level and ZappifyBug.com for wiki.naval.ch the zapper are easy to use. It has an LED that indicates when it is charging and absolutely-charged. We have not left it out in the rain to test the water-resistance.
