Awesome little lights! We put ours under our kitchen cabinets (the ones that hang on the walls, over the counters). They were very easy to install. They come with adhesive tape and screws so you can choose how you want to install them. They're small and have a low profile, we don't even notice that they are under the cabinets. The motion sensor part works quite well, they turn on as soon as we enter the kitchen. They stay on the whole time we are in the kitchen, and then turn off automatically shortly after we leave the kitchen. They're nice and bright and do a great job lighting up the counter areas at night. We haven't noticed them coming on during the brighter daylight hours. We're going to order a few more for our closets and pantries. These lights require 3 AA batteries EACH, so make sure to pick some up along with the lights!
