This is a large set, perfect for decortaing a lot of tables for an event. I have many sets of these, but the added remote is awesome. I can decorate ahead of time, and just walk in and hit the button on the remote and the rooms springs to life. In the past, I had to arrive early and go around to each table and remove the tea lights and turn them on. These are not rechargable batteries but will last a very long time with the LED lights. There is very little drain to the battery using them all night. Great set!
