We had pretty much given up on pantry lights as the kids would always turn them on and leave them, so battery powered was a pain.. these solve the problem. The light sensor means you don't have to bother switching on and off so the batteries last longer! Its so much easier and I can see the food again! The are heavy, very robust and use a huge bit of super sticky pad, but athe actual light is attached via a magnet to the wall pad, so you can grab it whenever you need to! The only problem is the children now like locking themselves in the cupboard as they can see whats in there too! Oh well you can't win them all.. great lights.
