[This review was collected as part of a promotion.] This technology seems to need work, so rather than being a useful house solution these have become a toy for my kids. And they love them! They even sleep sometimes with a light in their beds and have fun changing the colors. But my two complaints come from trying to use these lights under the kitchen cabinets. The battery life is so short and we were having to replace them every week; as well, the remote sensor seems weak as sometimes it would trigger a light change in all 3 lights, but other times only 1 or 2 would get the message. You've also got to walk pretty close to them for the remote to work.
