Not DC By Devon on 8/22/13
Devon wouldn't recommend this product to a friend
I got these to make a wave maker for my labs fish tank. I found out that they are not DC! They are 12V AC motors. That's a lie right on the box! I wasted so much time trying to get these to work. Once I did get it working, they seem ok. They are not particularly powerful but the nano is very small so it does not take up too much room in the tank.
