The lights work great but you need to be patient with the installation. For example, you need to work to get the bracket and fixure tightly together so you do not have a slight gap between the fixture and the drywall. Otherwise you are getting the same item you might find in a big box store by the same manufacturer. The four stars is because the remodel fixtures that are spring loaded into the drywall are a tighter fit but keep in mind you also need to spend more for the trim so trim is typically sold separately.
