If you don't always read instructions, you should be careful with this item. I did not realize that it was so sensitive to getting wet. It stopped working after about a week, and I found rust in the battery compartment. I must have gotten water in there and did not realize it. It should come with a disclaimer wrapped around the package explaining that you can only insert it into your aquarium to a certain level. Its in the garbage now.Hide
