I've owned this one for over a year and it is pretty impressive for its size and light output. I've never had any issues with it during stormy conditions and have two on either side of my gate which is useful when having to walk in total darkness. It can detect movement at distance and will stay on for 15-20secs approx. Useful if you have no light in dark places to walk into. The only disadvantage I can only think of is, that the light does not stay on long enough, but I am being really picky for this small light though.
