I love these and you get 4! I love that the tea lights and batteries come with it and I've never seen tea lights that have a sensor to go on in water and off when you take them out. One of my tea lights only lasted a week and they were only on at night, but the others have been fine. Just keep in mind that they take button batteries and they can be expensive depending on your use for them. Modgy has been a great company to order from, they are very quick with fulfilling orders. I placed an order about 6 hours ago and I already have an email that it has been shipped!!
