Product review (1 stars): This is ONLY a Transmitter, Not the Kit
Important note:  This is ONLY the transmitter. You will also need a receiver to control anything, lights, etc. Quite frankly, it is overpriced here. Get the entire kit with the receiver from HomeDepot for under $20. I paid $25 for just the one part on Amazon. From the reviews, you would think this is all you need--it isn't. The receiver is sold separately.
