I received the Wireless LED Puck Lights in exchange for my opinion.  The lights are very easy to install and come with 3 AA batteries.  They are easy to install and come with both screws as well as double sided tape.  The lights are very bright and really do a great job lighting up dark closets.  I like that you can use the same remote to control up to 12 Puck lights.  I also like how you can adjust the brightness of the lights.  Very pleased with this product and will be purchasing more to brighten up additional areas of my home.
