Do not buy this item unless you intend to mount the unit South-facing in plenty of direct sunlight.
After charging outside our house (South-facing for 3 days) and mounting the wedge on a northwest wall, which has plenty of ambient light, but not too much direct sunlight, I am finding it will only work for a day or so before losing charge again and therefore needs unmounting. It may work better during other seasons, but that defeats the object.
When it works the motion sensor is great and it's plenty bright enough, but I expected to put the unit up and never to have to move it in its lifetime.
Maybe I'm expecting too much, but many other other solar items will function with minimal light nowadays, which is not the case here.
