These arrived really quickly, I love these lights, they are really bright and the motion detection works well. I found that it's better to use something pointy to press the lighting mode switch as it didn't work with just my fingers. To the buyers that said theirs didn't work, give that a try hopefully it should turn on. I have installed mine on to a piece of wood with a couple of hooks on the back so they can be moved around anywhere to hook onto a patio, garage or even just placed on the floor. I've bought similar lights with only 10pcs led and they have lasted years in all weather and are still going strong. I totally recommend this product, it does everything it says in the description and is very good value for money.
