I recieved a 2 pack of puck lights with remote to try out. I am absolutely thrilled with them! I've actually been looking for some for under our kitchen cabinets and have never seen puck lights with a remote! It's awesome! They were super easy to hang. They take 3 AAA batteries... the remote already has a battery in it. The remote makes it so easy to turn them on, off, dim the light, put on a timer. I was pleasantly surprised with how many functions it had! I will be purchasing at least 4 more of them for in the kitchen but they would be great anywhere! I HIGHLY recommend them!
